In this second installment of our DIY Ethereum mining guide, we’ll look at how to install and configure Linux to setup your rig as an automated, remotely-manageable appliance. Don’t be dissuaded if you’ve never used Linux before—our step-by-step guide makes it simple!
Why Linux over Windows? First, it’s free—and saving ~$100 on the operating system is a big plus when you’re trying to maximize profitability. Other reasons include lesser hardware requirements (Linux is perfectly happy running from a USB stick plugged into ancient hardware!), simpler remote administration capabilities, and oftentimes better stability. The downside of running Linux is that video driver support isn’t on the same level as Windows, and things like GPU undervolting are trickier (but still possible via BIOS mods).
If you missed the hardware portion of our guide, make sure to check it out first. Otherwise, read on.
Build an Ethereum Mining Rig, part 2: Linux Setup
The following is heavily adapted from my original 2013 Litecoin mining guide, updated for the latest Xubuntu LTS version, the new AMDGPU-PRO drivers, and necessary ethereum mining software (all up-to-date as of 11/29/2017). If you’re a bit nervous because you’ve a complete Linux newbie, don’t be. Simply follow the step-by-step instructions exactly as they’re written, and you’ll be fine. Even if you’ve never done anything like this before, you should be up and running in roughly an hour.
Step 1: Configure BIOS settings
Before we even get to Linux, let’s take a minute to make sure that your mining computer’s BIOS settings are in order. Power on your computer, and press the “delete” key a few times immediately after power on. You should end up in the BIOS configuration area. Do the following, then save & exit:
- Change power options so that the computer automatically turns itself on whenever power is restored. The reason for this is two-fold: first, it’ll make sure that your miner automatically starts up after a power outage. Second, it makes powering the computer on much easier if you don’t happen to have a power switch connected to the motherboard.
- Make sure that your USB stick is first in the boot-up order (you may need to have a USB stick attached).
- Disable all components that you don’t plan to use. This may save a little bit of power, and since your miner will likely be running 24/7, it’ll add up. For me, that meant disabling onboard audio, one of the SATA controllers, the USB 3.0 ports (I only had a 2.0 USB stick), the Firewire port, and the serial port.
- If you’re running a lot of GPUs (4+), additional tweaks might be necessary to ensure that they’re all recognized by the OS. Exact tweaks vary by motherboard, but setting the PCIe speed to Gen1 is usually a good place to start. No need to change anything now, but make a mental note that you may need to come back and play around a bit if all of your GPUs don’t show up in the OS later.
Step 2: Install Xubuntu Desktop on your miner
Xubuntu is a lightweight version of Ubuntu, a popular Linux distribution. Most other distros should work just fine, but be aware that the GPU drivers require the presence of Xorg, which means server distros that don’t have a GUI will not work properly.
- Xubuntu 16.04.3 is the latest LTS release at the time of this guide, so that is what I recommend you use. You can download it here.
- You’ll need to either write the installation ISO image to a USB stick (highly recommended), or burn it to a DVD. If you use a DVD, you’ll need to temporarily hook up a DVD drive to your mining rig for the installation (make sure you temporarily enable your SATA controller if you disabled it in step 1!).
- Once you have the installation media prepared, you’re ready to install Xubuntu to your miner’s boot device (whether it’s an SSD, mechanical harddrive, or another blank USB stick). Boot using your new installation media (make sure it’s first in your miner’s BIOS boot order list). The Xubuntu installer should appear.
- Follow the prompts, and make sure to click the “auto-login” box on the last step of the installer (otherwise, all of the default options are fine).
- When the installation is complete, you should automatically boot into the Xubuntu desktop. Make sure to remove your installation media.
Step 3: Install SSH and package updates
At the Xubuntu desktop, press CTRL+ALT+T to open a terminal window.
- Install SSH by typing:
sudo apt-get install openssh-server
With SSH installed, you can unplug the keyboard/mouse/monitor from your miner, and complete the rest of the installation from your desktop computer. Simply download Putty onto your desktop, run it, and enter the IP address of your mining rig (type ifconfig at the Xubuntu terminal to find your miner’s address if you don’t know it—it will probably look like 192.168.0.x). That should bring up a remote terminal session to your miner, which is more or less just like sitting at the keyboard in front of it.
If you plan to manage your mining rig remotely over the internet, you’ll need to forward port 22 on your router to your miner. Make sure that you use a strong Xubuntu password!
Setup should be pretty quick from this point, as now you can simply copy text from this webpage (highlight it and press CTRL+C) and then paste it into your Putty session by simply right-clicking anywhere inside the Putty window. I highly recommend that you complete the remainder of the guide in this manner, as it eliminates the risk of typos!
- Install package updates by typing (or copying & pasting via right-click into Putty) the following command:
sudo apt-get dist-upgrade
Step 4: Install AMDGPU-PRO drivers
Next up, we’ll install AMD’s video drivers. AMD has special blockchain compute drivers available for mining that give far superior performance compared to their standard drivers, so that’s what we’ll be using (version 17.40, which is the latest as of 11/29/2017).
- Type the following commands (press “enter” and wait for the operation to complete at the end of each line):
cd ~/Downloads wget --referer=http://support.amd.com https://www2.ati.com/drivers/linux/beta/ubuntu/amdgpu-pro-17.40-483984.tar.xz tar -Jxvf amdgpu-pro-17.40-483984.tar.xz cd amdgpu-pro-17.40-483984 ./amdgpu-pro-install -y - Some of these steps may take a minute or two to complete. When the installation is complete, type the following:
sudo usermod -a -G video $LOGNAME - Next we need to install and configure the ROCm component:
sudo apt install -y rocm-amdgpu-pro echo 'export LLVM_BIN=/opt/amdgpu-pro/bin' | sudo tee /etc/profile.d/amdgpu-pro.sh - Finally we need to enable large page support, which will dramatically improve mining performance. Type the following to open your grub file in nano for editing:
sudo nano /etc/default/grub - Find the line that reads GRUB_CMDLINE_LINUX_DEFAULT=”quiet splash”. Modify it to:
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash amdgpu.vm_fragment_size=9" - Save the file and quit nano by pressing CTRL+X and then answering (Y)es to save the changes. When you’re finished, update grub and reboot:
sudo update-grub sudo reboot
The final command will reboot your rig, which will cause you to immediately lose your SSH (Putty) connection. Wait a few seconds to give the computer a chance to boot, and then re-establish a new connection via Putty, and re-login.
Step 5: Install Ethereum software
(Note: you may skip step 5 entirely if you already have an ethereum wallet address that you intend to use!)
Next up, we’ll install the Ethereum software that will let us create a new wallet address. We’ll need this to store the coins we receive from mining.
- Type the following to install the necessary ethereum packages:
sudo add-apt-repository ppa:ethereum/ethereum sudo apt-get update sudo apt-get install ethereum geth - Now it’s time to create your Ethereum wallet address:
geth account new
You’ll be prompted to enter a password, and then to confirm it (use a strong password!). The output will be a long string between two curly braces { }. That’s your new wallet address—make a note of it (highlight it within Putty to copy it to your clipboard).
Important: The combination of the password you just used to create this address *and* the associated encrypted key file is what gives you control over your new wallet address. If you lose either of these, you’ve also lost control of your wallet and all of the coins associated with it—and there is literally nothing that anyone will be able to do to help you. Remember your password, and keep multiple backups of your key file(s)!
Your key file(s) are stored in the ~/.ethereum/keystore directory. Copy the entire /keystore folder someplace safe to backup your wallet (backups are covered in more detail here—don’t forget to make multiple backups and keep them in a secure offline location!).
If you forget your wallet address, you can type geth account list to see your addresses and the location of their key files.
Step 6: Install Claymore’s Ethereum miner
There are several options as far as mining software, and I’ve experimented with all of the popular ones. I think Claymore’s miner is the best option, even if it does have two fairly significant downsides: it’s closed-source, and it’s not free (~1% of your mining time benefits the creator of the miner).
Two alternatives are the stock ethereum miner (ethminer) and Genoil’s fork of the stock miner. They’re both open-source and free, but they have pretty crippling downsides.
The stock ethminer is much slower than Claymore’s miner (by a margin of over 5% on my test rig). In addition, ethminer creates the Ethereum DAG file on disk instead of in GPU memory, which is slow and uses a lot of space (and if you’re running off a USB stick, all those writes may eventually wear it out).
Genoil’s fork seems to be nearly as fast as Claymore’s, and it doesn’t use physical disk space for the DAG, but it’s not stable (at least not for me). It often crashes, especially on startup (whereas I have yet to see a single crash on Claymore’s miner after nearly a week of full-time mining). The author abandoned development months ago, so improvements are unlikely.
So, explanation aside, here is how to setup Claymore’s miner:
- First return to your downloads directory and grab the latest version (10.2 as of 11/29/2017). I’m pulling the file directly from the author’s Google Drive repository, if the link is broken check here for a newer release or updated link):
cd ~/Downloads sudo apt install curl curl -L -o claymore_10.2_miner.tar.gz https://drive.google.com/uc?id=1t25SK0lk2osr32GH623rR8aG2_qvZds9 - Then create a new directory for it, and unpack it there:
sudo mkdir /usr/local/claymore10.2 sudo tar -xvf claymore_10.2_miner.tar.gz -C /usr/local/claymore10.2 - Then let’s head over to the installation directory and create a startup script. Note that commands 2-5 below just clean up the installation directory a bit by removing an intermediary directory that was included in the original tar archive:
cd /usr/local/claymore10.2 cd Clay* sudo mv * /usr/local/claymore10.2 cd .. sudo rm -r Clay* sudo chown root:root ethdcrminer64 sudo chmod 755 ethdcrminer64 sudo chmod u+s ethdcrminer64 sudo nano mine.sh - Nano will open a new blank text file; enter the following into it:
#!/bin/sh export GPU_MAX_ALLOC_PERCENT=100 ./ethdcrminer64 -epool eth-us-east1.nanopool.org:9999 -ewal YOUR_WALLET_ADDRESS/Miner01 -epsw x -mode 1 -allpools 1 -tt 68Where it says YOUR_WALLET_ADDRESS, use the address you created in step 5 (you’ll need to put “0x” in front of it). The “Miner01” following your address can be changed to any friendly label that you want to give your miner (only important if you plan to run multiple rigs). It’s easiest to copy the last line from my guide into something like notepad, then replace YOUR_WALLET_ADDRESS with your actual address there, and then copy the finished line into putty via right-click to get everything into nano without typos.
- Save the file and quit nano by pressing CTRL+X and then answering (Y)es to save the changes, then enter the following to give your new script execute permission:
sudo chmod +x mine.sh
Note that I’m using nanopool.org as the mining pool here. I’ve tried a few, and it seems to be a top pick, but feel free to pick your own pool. Most don’t require registration, and simply payout to whatever wallet address you supply whenever a certain threshold is met (usually whenever you accumulate 1+ ETH). Assuming you stick with Nanopool, you’ll be able to check on your miner’s status by going to this URL after you start mining: https://eth.nanopool.org/account/[YOUR WALLET ADDRESS]
- Now is a good time to test things. You can fire up your miner by typing:
./mine.sh
You should see the Claymore miner start up. It’ll take a minute or two before it actually starts mining, but it should get there eventually. When you see a scrolling log of outputs that includes non-zero hashrates (expect hashrates in the low to mid 20s for unoptimized GPUs), you’re good to go. If the script fails to start, or you see errors, make sure that you’ve created the script exactly as outlined in the guide.
Press CTRL+C to exit the miner when you’re satisfied that it’s working.
Step 7: Create auto-start scripts
We’re almost done! We want to set up our rigs automatically start mining whenever the rig is powered on. That way, we keep mining losses to a minimum whenever a power outage occurs, and we don’t have to worry about manually starting it back up in other situations.
- First, install screen:
sudo apt install screen - Then type the following to create a new script in your home directory and open it in nano:
cd ~sudo nano miner_launcher.sh - Enter the following text into the editor (substitute your actual Xubuntu username for YOUR_XUBUNTU_USERNAME where necessary!):
#!/bin/bash DEFAULT_DELAY=0 if [ "x$1" = "x" -o "x$1" = "xnone" ]; then DELAY=$DEFAULT_DELAY else DELAY=$1 fi sleep $DELAY cd /usr/local/claymore10.2 su YOUR_XUBUNTU_USERNAME -c "screen -dmS ethm ./mine.sh" - Save and quit nano (CTRL+X), and then type:
sudo chmod +x miner_launcher.sh - Now we need to call our new script during startup; we do that by adding it to /etc/rc.local. Type the following to open /etc/rc.local in nano:
sudo nano /etc/rc.local - Add the following text, right above the line that reads “exit 0” (substitute your own username!):
/home/YOUR_XUBUNTU_USERNAME/miner_launcher.sh 15 &
Then save and quit out of nano (CTRL+X).
Step 8: Create an alias to easily check on the Claymore miner process
We’re essentially done at this point, but you’ll probably want to manually SSH into your miner from time to time to manually check on your hashrates & GPU temperatures, etc. Creating an alias will make that easy.
- Type:
sudo nano .bashrc - Scroll to the end of the file, and then add this text above the line that reads “# enable programmable completion…”
alias miner='screen -x ethm' - Save and quit out of nano.
That’s it—you’re done! You’ll probably want to run a full test now. The easiest way to do that is to close your Putty session and power down your miner. Turn it back on and the following should happen:
- Your miner should boot into Xubuntu. This may take up to a minute, depending on the speed of your boot device (it’ll be much faster on an SSD).
- 15 seconds after Xubuntu has loaded, the Claymore miner will automatically start and begin mining. You might notice the fans on your GPUs spin up a bit when this happens.
- You should be able to SSH into your miner at any time and type miner to monitor the miner’s process. To close the screen (but keep the miner running), press CTRL+A, then CTRL+D.
- If you ever need to start the Claymore miner manually (because you quit out of it, or kill it, etc), simply type ~/miner_launcher.sh
(update 1/15/2018: **IMPORTANT** please read this if your hashrate is lower than expected!)
Output from a single budget RX 470 at stock settings running Claymore’s ETH miner. You should see something like this when connecting to your rig via SSH and running your “miner” alias.
Congratulations—you have your own headless linux ethereum miner!
The next section of this guide covers setup under Windows, and then we’ll take a look at optimizing miner settings for better performance.

Do you happen to know why I keep getting the line :
Failed to set new fan speed, check if miner has root access!
printed continuously while the miner is running? The Fans seem to remain at around 50%.
are you root? try throwing a sudo in there
I have the same problem. I have added sudo before the command ./mine.sh but same results. Also, I went back and made sure the file permissions are set to Group: sudo Access: create and delete files. So, as far as I can tell, I’ve set the permissions to allow root access, but I still get the error. “Failed to set new fan speed, check if miner has root access!”
Any help you can offer would be much appreciated! Thank you!
Anyone stuck here to and find a solution ? Thank you!
Hello guys,
I have this problem.
Whe I start ./mine.sh file, happens this thing:
./ethdcrminer64: 1: ./ethdcrminer64: Syntax error: Unterminated quoted string
This is the mine.sh file:
#!/bin/sh
export GPU_MAX_ALLOC_PERCENT=100
./ethdcrminer64 -epool us1.ethermine.org:4444 -ewal MyADDRES.Miner01 -epsw x -mode 1 – tt 68 -allpools 1
Can anyone help me please?
Ciao.
Nico
in the part that says “MyADDRES.Miner01” shouls say something like “0x54015154054015604504.computer01” where “0x54015154054015604504” is the adress that you got in step 5, “computer01” is the name of the PC you’re mining from
Yes you are right…
I write exactely what you written, but it is not working…
You must write YOUR information, the one I posted is an example of how it should look, as I don’t know your wallet address nor your mining rig name
Yes i do what are you written…
And remember to add the “0x” at the beggining of your wallet address, as the output in step 5 doesn’t included it automatically
Ok guys..
Many thanks for the feed-back.
To be clear this is what i written:
#!/bin/sh
export GPU_MAX_ALLOC_PERCENT=100
./ethdcrminer64 -epool us1.ethermine.org:4444 -ewal MyADDRES.Miner01 -epsw x -mode 1 – tt 68 -allpools 1
Where: MyADDRES is 0x….bla bla bla from “geth account new” command line.
Miner01: i leave this infro as is. If it is not whre I can find the info I have to put in?
Many thanks again to all the forum!!
Nico
In every new terminal window says something like: “nico@miner01:~$”, where “miner01” is the name of your computer, the one you must input in the mentioned command.
It looks like there is a space in ” – tt” between the dash and the first t; change that to “-tt” and it should work
hey, got a problem with my rig! installed sam xubuntu as you – but it seems like my RIG goes in some kind of “idle” state. reported hashrate keeps up, but i dont generate shares after leaving the rig about 30 minutes online – anything i can do?
Hi. Great write-up. So far, this is the guide I’m following. For now, I reached an issue. I bought RX 580, RX 570 and GTX 1070s. Following your guide, I was able to install AMD drivers. Before actually start mining, I installed Nvidia drivers as well, for GTX 1070. Nvidia requires installation of driver in TTY, so that’s what I did. After installation, of Nvidia, with both AMD and Nvidia connected, Ubuntu 16.04 LTS won’t boot into gui anymore.
Removing AMD card allows me to go into gui once again.
Any ideas?
hi, sadly you are not suppost to mix AMD-Cards with Nvidia ones. There are also problems mixing different types of AMDs aswell!
I would recommend a fresh-install with either only AMD cards or NVIDIA ones!
That’s not good news 🙁
Follow-up question, you mean it’s also not recommended using GTX 1070, and 1080 on same rig?
Will mixing AMD and Nvidia be solved if using Windows 10?
I solved the issue of mixing nvidia and ati cards using 1 monitor in the ati GPU and 1 monitor in the nvidia GPU, in my case pc boots in ati monitor, but once xubuntu starts the desktop goes to the nvidia monitor and claymore ran without problems. I don’t know if it is related to the order the drives where installed or the slot used by each GPU, anyway I tested only with 2 GPUs without risers, so I don’t know if you have more gpus you need more monitors or even if will it work… I opted for use only one kind of GPU in each rig, no problem in mixing rx470, rx560 and rx570 from diferent manufacturers in my case, I guess it depends on the motherboard you use.
I, on the other hand, use Gigabyte, with 6 pcie slots. It has onboard VGA port, using Celeron G3930. I have monitor plugged to the motherboard. Only connected Nvidia and AMD cards to HDMI, and HDMI input of monitor (accepts both VGA and HDMI). It’s where I see no output when in HDMI when AMD present.
Hi,
Is there any merit to the preloaded mining OS SSD’s etc? I’ve been looking at buying the ethOS Mining OS, just because I have to buy a SSD or boot device anyway. Thoughts?
Hello, i have a few months with a few rigs all wuth xubuntu because i get more hasrate than windows. But i have a problem with graphic interface, them i install the amd drivers and reboot, never get up the x interface again. Thats not a bit problem i just use a console, but untill now i dont kniw why that is happening. I have the same problem with all the rig, no matter if it have 1 or 6 gpus ot the model of the cards, just the interface never work. Sorry i am liying in 1 pc work, an old one. If you can give me any idea what to check i will apprecuate. Thanks.
Is geth not working for others?
hey guys new here but I was able to follow along and I’ve got everything running so far. Except checking the status of the miner. the line: alias miner=’screen -x ethm’ doesn’t appear to do anything for me. When I type miner i get “Three is no screen to be attached matching ethm”
Any clues on how to fix that?
does your miner_launcher.sh run without failure when executed manually? it shouldn’t.
ps aux | grep screen
if you don’t see an entry for screen there,
sudo apt-get update
sudo apt-get install screen
then retry miner_launcher.sh
hi, thanks for your article, all works, Exept:
I get a password prompt everytime I run miner_launcher.sh on my Ubuntu 16.04
What should I do to get rid of it?
if you have not rebootet yet, just du it – if it does not work then, most likely its a typo in one fo your script-names, or you have not downloaded a tool correctly via apt-get install!
you can just re-type every apt-get command, and see if it starts to update/download one of them. could fix your problem!
if not, there is a problem with one of your “handmade” scripts!
I think the reason is the following string:
su YOUR_XUBUNTU_USERNAME -c “screen -dmS ethm ./mine.sh”
I’ve changed su->sudo and YOUR_XUBUNTU_USERNAME to my username
my line sounds like the following:
“su eth0 -c “screen -dmS ethm ./mine.sh”
since eth0 is the username of my rig.
dont change su to sudo because the string interprets “su” as super-user and can run it without typing the passwort there
my sting is
su denis -c “screen -dmS ethm ./mine.sh”

Thanks!!
sounds like you overclocked the cards to heavily, i had the same issue
i dont overclocked the card by myselfe, but maybe the previous owner 🙂 sounds like i must check this…
thanks
did the previous owner mine alt-coins aswell? if so, It sounds like you need the origibal bios
i think he was only a gamer.. but i will check the gpu with my windows pc…
I’ve found the problem.
It was my firewall 😉
Great guide nice work and well done.
One additional step you might mention is that at the end of step 4. I had to download a custom driver for Nvidia, using the ubuntu panel) and then run it to switch to using the nvidia driver instead of the default driver. Without this Eth did not recognize my cards.
Also a quick guide to re-using your Eth miner address from a different rig would be helpful. Again Eth would not run with a key file and a tutorial on how to copy that from another system would be helpful
thanks and Mine-on!
richard
im kinda having this problem too. complete noob here not sure on how to install nvidia drivers for the gpu. so far this is what i gathered. anyone can verify?
Since most of these answers are outdated… Here is modern way to install the nvidia drivers for Ubuntu (for 14.04 and newer):
All you need to do is:
Add the graphics-drivers ppa
Install the recommended Nvidia driver
Restart your system
so, from a terminal, run:
sudo add-apt-repository ppa:graphics-drivers/ppa
sudo apt-get update
sudo ubuntu-drivers autoinstall
sudo reboot
that’s all there is to it!
note: if you want to install a specific version of the graphics driver, you can see which drivers are available for your hardware by running: sudo ubuntu-drivers devices, and inspecting the output to see which drivers are supported. Then just install normally with, for example, sudo apt-get install nvidia-381
Does anybody know how to reattach “screen” with miner_launcher.sh?
there is no screen attached to it after a restart!
That hapen to me when autostart doesn’t work, if in terminal you go to /usr/local/claymore95 directory and run ./miner.sh it work fine, so I think is something about failed autostart
If you’re seeing a message that there is no screen attached to ethm or something similar, there is likely a typo in your miner_launcher.sh script that is preventing it from starting your miner properly.
Try running ./miner_launcher manually – if it’s working properly, you won’t see anything happen immediately after running it, but typing “miner” afterwards should take you the screen session that claymore is running under. If typing “miner” gives you the “no screen attached…” error after you’ve executed miner_launcher.sh, you’ll need to check your miner_launcher.sh script for errors.
I used linux guide above to create my Ethereum wallet account, with geth account new, kept the address safe, and remembered the password. Unfortunately, due to difficulty in settling up mix mining, I moved to Windows. I wasn’t able to save my key. I’m only a few days in. Is it still possible to retrieve key using password, address alone (in windows 10 this time). Or is it easier to just start over now. I’ve only mined .116 ether for now, since not yet full blown yet. Still in experimental stage. your immediate advice will be helpful.
Thanks
Unfortunately you can’t access the ETH in a given wallet address without the associated key file. If it’s no longer possible for you to recover the key file (do you still have the linux drive?), you’ll probably have to write off any ETH stored there.
Hi. I used your guide to set up my miner and it is working very well, but I do have question. How do you shut down the miner with SSH?
You can type “sudo shutdown now” (without the quotes) to shutdown via SSH.
hello all,
first time here,
So i have a couple problems.
When I restart my machine it does not automatically restart mining.
when I type the code /miner_launcher.sh it does not work?
any idead
Most likely you have a typo somewhere – do you see any errors when running the miner_launcher.sh script?
I copy pasted every line.
when type /miner_launcher.sh it says no such file or directory, when i type ~/miner_launcher.sh it asks for a password and then does nothing just pops up the felix@felix:~$
Make sure you have a dot (period) in front. First make sure that you’re in your home directory (type “cd ~” without the quotes). Once there, you should be typing “./miner_launcher.sh” at the command prompt (without the quotes, note the period at the beginning).
I tried that and it does not work. Nothing happens after asking for a password.
I tried going to cd /usr/local/claymore95 then type ./mine.sh but starts the mining process but i fails and i have to close putty and reopen it.
Maybe is there a way of restarting like erasing the files i have and restarting at step 4 or 5?
fyi im using an msi rx 580 8gb
When I go thre /usr/local/claymore95 then type ./mine.sh i get this message
“This pool (eth-eu2.nanopool.org) does not support Ethereum addresses as login (or requires worker name in “Login.Worker” format) and cannot be used for devfee mining, therefore it is not supported.”
plus a bunch of “however…”
its working now. Thank you Crypto Badger
Why Xubuntu instead of Ubuntu?
It’s because the low hardware requirements, Ubuntu needs more ram and a bigger graphics card, while xubuntu with xfce graphic enviroment, and lower hd space is all you need, but as far as I know the guide described here works in Ubuntu too
I see. But if you just SSH in, it will it be that much of a difference?
yes end no – ubuntu will still need more ram and other resources. its not all about the gpu.
if you are for example also cpu mining, using xububtu will give you an actual benefit, because your cpu can work more freely without running much co-processes of ububtu
You can use Xubuntu or Lubuntu or the base of them: Ubuntu, the fact that Ubuntu have higher hardware requirements impact in power consumption at long term.
Cryptomining is all about ROI, lower the initial cost and lower the running cost, sooner the ROI is achieved, and higher is the profit, so if you purchase for your mining rig 8Gb of RAM to run smootly Ubuntu in a new dedicated monitor, or recycle a 2Gb stick to run Xubuntu via SSH is up to you… and your profit.
im getting an error message and i used to mine at around 21.4 Mh/s (rx 580 8gb) but now im only mining 10.5 Mh/s.
error message is
“server: bind failed with error: 98 (check -mport option value), next attempt in 20sec…”
anyone can help please?
im dual mining ether and sia
#!/bin/sh
export GPU_MAX_ALLOC_PERCENT=100
./ethdcrminer64 -epool us1.ethermine.org:4444 -ewal 0xf501d[xxx]7cec36.Miner01 -epsw x -dpool stratum+tcp://sia-us-east1.nanopool.org:7777 -dwal 023d8d[xxx]72d5e12fbe16ef3 -dcoin sia -dcri 16 -tt 68 -allpools 1
Try try adding -mport 0 option. This kills remote monitoring, but will get you mining.
I’m mining with Xubuntu using an AMD RX 580 OC. It’s running at about 71C with a fan speed of 22%. I’d imagine that it would automatically increase the fan speed at this high temperature. However, it is not. Does anyone know how to control the fan speed through command line. Or any better suggestions would be appreciated. Thanks!
Don’t worry, lower 70’s is “normal” working temperature, remember it’s working at full load, and no momentary spikes like in gaming, even high 70’s is aceptable if fan works at 100%, but if it’s in 80’s range you should worry and consider extra fans or even air conditioning. I use 4x 120mm fans to aid in cooling 6 GPUs rígs and keep it’s fans under 50% load, it’s quieter and increases GPUs fans life
you can increase the fanspeed automaticly by setting a lower target temperatur in claymore miner!
i am using “-tt 58” at the moment for a temp of 58°C
58 is very low for mining, if you Environment-temp is high, your fans will run very fast wich hurts the gpu over several months!
my environment temp is only 18°, so im still running at 19%
Hi
I just got a rig set up with two cards, running linux, but when I start mining, it displays GPU temp and fan speed 4 times, then in red displays ‘Miner thread hangs, need to restart miner.’
It does this immediately, the GPUs never get past 0.00MHs when checking them by pressing ‘s’.
The only key difference I see it that I am running Linuxmint, not Xubuntu.
Thanks.

It’s normal that the first 2 hash output are zero, and the GPU temp display a couple times, then it starts to mining in the expected hashrate, but if it never normalize speed maybe you’re pushing the overclock too far up, in case you’re not overclocking maybe you’re using wrong drivers
Thanks for the reply.
My issue was in the drivers. I went to older drivers as the v384 wasnt working.
v370 worked for my cards, they are running stable as can be.
Not always newer is better, 375 is the newer drivers I have tried, and as far as I know haven’t any issues, if 370 work for you stick with it
Hi cryptobadger, im using radeon 295x2s and seem to cant get the right drivers/configuration. should i still be usuing this version of ubuntu and what driver installation should i be using? thanks so much for putting together such a fantastic tutorial!
Awesome guide thank you so much for sharing, and great pick to use xubuntu!
Hi there, thanks for putting this excellent how-to!
I have just installed Ubuntu via netboot and choosen Lubuntu and ssh as packages, did the whole process but when I start ./mine.sh I get ;
./ethdcrminer64: error while loading shared libraries: libcurl.so.4: cannot open shared object file: No such file or directory
I have used amdgpu-pro-17.30-458935.tar.xz instead of amdgpu-pro-17.10-414273.tar.xz in case this could be it but I doubt??
Can someone please help me out? FYI I got 3 cards connected but only using onboard intel graphics via DVI on H110 mobo and G3930 Celeron CPU.
Hi,
What does the 15 at the end of “/home/YOUR_XUBUNTU_USERNAME/miner_launcher.sh 15” in rc.local do?
