Cool thanks

you my friend forgot step #7 or are installing the nvidia driver that doesnt have CUDA.

you may need to manually set the ID's in the config.xml file like this:
 

<slot id='1' type='GPU'>
<gpu-index v='0'/>
 <cuda-index v='0'/>
 <opencl-index v='0'/> </slot>
 <slot id='2' type='GPU'>
 <gpu-index v='1'/>
 <cuda-index v='1'/>
 <opencl-index v='1'/>
 </slot>
 <slot id='3' type='GPU'>
 <gpu-index v='2'/>
 <cuda-index v='2'/>
 <opencl-index v='2'/>
</slot>
 <slot id='4' type='GPU'>
 <gpu-index v='3'/>
 <cuda-index v='3'/>
 <opencl-index v='3'/>
</slot>
 <slot id='5' type='GPU'>
 <gpu-index v='4'/>
 <cuda-index v='4'/>
 <opencl-index v='4'/> </slot>

That makes no sense... you wouldnt still happen to have the log would you?

That makes no sense... you wouldnt still happen to have the log would you?

Sorry, for taking up so much time. I needed to make sure that my system is as close to yours as possible. Also to make sure that it is functional under windows. So I grabbed a second Ti from a friend, ran it for a whole day under Windows (both ran fine) and then re-tried your guide. Even used the drivers that were current at the time of your write-up. Still same issue, my slots even failed at some point. I attach the log: https://ufile.io/v4bpa (slow download -> unzip)
 
Also I did not play with coolbits one bit, nor do I installed TeamViewer, so I followed your steps *exactly* up to step 8 (sans the teamviewer installation). I can even give you a teamviewer connection if everything else fails, I'm determined to make this work. From reading the log I can see that it does not detect the cuda cores, even though I install the nvidia-381 drivers, even as I manually assigned the cuda slots... So what's your take on this?
 

Chris21010
try driver 381.22-0ubuntu0-~gpu16.04.2 its the one i am currently running. you may need to go to the software manager again and open the PPA to see the full list of installs.

 Yes! That's exactly the version I'm running (nvidia-381 = driver 381.22) and installed exactly though the way you've said within your guide. I mean I followed your guide exactly, even used the name "mintuser" lest the username could somehow change anything (it wouldn't).
BTW is the log telling you anything additional? (other than that CUDA cores are not found). Funny things is that I'm even using the GPUs as in your guide and generally did everything apart from coolbits (which IMO should not change anything).
 
Slots keep failing on me though all the same ... probably I'd need to install ubuntu 16 for a change? Dunno, I'm at my wits' end. Also I noticed that your coolbits part is written for GTX 1070s , have you -maybe- did things slightly differently with your your GTX 1080 Ti rig and that's why I'm getting the showstoppers (i.e. the GTX 1080Tis need something additional not written on the guide?).
 
If you "refollow" your guide using Mint Linux and driver 381.22, are you going to get the same result as me? (on your Ti rig)

Chris21010
at this point the last thing i can think of is try installing the CUDA toolkit. F@H log states no CUDA, which there should be. i honestly do not know enough about linux to really help diagnose the true issue or to even see if the CUDA libraries are installed or not. i know this is your issue but not how to correct it. the xorg.conf shouldn't have play here, i believe, and the default one created at install should be fine.

As it turns out the issue was with nvidia-381 (of all things). So I "reverted" to nvidia-384 (latest version of nvidia drivers) and everything worked. So the showstopper was following your guide *exactly*. I don't know why or how but nvdia-381 simply does not work on my system. So yeah, I'm happilly folding at this point. It took 3-4 days to realize that there was definitely something wrong with the drivers themselves. I am still not sure what, what I do know is that whatever it was installing nvidia-384 on top of nvidia-381 solved it...
 
So I'm happy owner of a Mint-based folding rig. Thanks for the guide, here's hoping for less inconsistent drivers in the future. Let this also be a lesson for future would-be folder, if cuda cores are not recognized, simply install the latest nvidia drivers on top... It worked for me, it would probably work for you too...

So finally got this build working, and it's unbelievable.  I have my 1080FTW folding on an A6-5200.  When it was in windows, the 1080FTW was starving, and was only getting 360k PPD, when I installed Mint, the card is doing gangbusters better than it was doing when it was in my Xeon.  I needed to split my cards up since the current drivers for the 1080Ti suck so badly for the 1080's for folding.  So I have the 1080's in 2 different machines, 1 offsite as a space heater (in windows), 1 in the basement as a space heater and my 1080Ti in my main rig.  I am flabergasted that Linux has such a difference in needs of processing power for feeding the cards.  WOW.

But once you get a setup working, it becomes almost trivial to clone it - if you use the same MB and semi-close on the GPUs.

I think I found something interesting for your tutorial Chris. 
https://github.com/RunGp/Nvidiux
 
Nvidiux is a graphical python tool to overclock or underclock your nvidia gpu

you may need to update the OS before you can install. that or try downloading it again as i recently had errors on install till i downloaded it again.

if it says it doesn't exist you'll need to create the directory first. as for F@H not starting at boot, that is something i haven't ran into as its setup to do that be the default install. try giving it a reinstall and see what happens.

I've followed this guide with 2 rigs now, 1 with 4 1080tis and the other with just 1. All running great for a month or so.
 
I just brought 2 new 1080tis to put in the second rig. However, when I did so it seemed to mess up folding. I now can't get any of the 3 gpus in this system to fold! I have the following log:

Any help would be much appreciated!

Wow thanks for the quick reply Chris. Your last comment about a bad board got me thinking and I remembered this board has a supplemental sata power connector for if you add more than 2 cards. I connected this and hey presto it worked! 
 
Thanks again

Hi, 
 
I recently followed your guide to get my mining rig up and running and after step 9, my display is locked at 480p. It says my monitor is not detected, etc. Just like if I had no nvidia graphics installed. I am so confused, please is there any customization for different configurations of cards needed? Is it necessary to do step 9-11? Thanks
