Installing F@H on Linux Mint for GPU Crunching

Sorry if this is the wrong forum for this.

Just thought I'd point out that as of September, 2015, the latest .deb installers for the F@H Client don't include the GPUs.txt file and mysteriously still don't auto-fetch it, so I was getting the infamous "On client "local" 127.0.0.1:36330: No available GPUs" error.

If you want to enable a GTX 970/980 for crunching on Linux, you still need to download

https://fah-web.stanford.edu/file-releases/public/GPUs.txt

and drop it in

/var/lib/fahclient

then

sudo service fahclient restart

Don't forget to chown it for the fahclient user, too, or the client service won't start.

That is all.
 
A linux Mint thread, and a Linux Mint question from a newbie...

Anyway to wipe the video drivers clean and start over? I guess I downloaded the wrong package from AMD the first time, it wouldn't install, so I started picking and choosing libraries that sounded right.

BOINC recognizes the GPU finally, but all GPU tasks instantly result in computational error. I'm guessing if I can start over regarding the vid drivers, and choose the correct AMD download, all will be well.

If you downloaded the package from AMD and used apt-get to install it?

Code: 
sudo apt-get remove --purge fglrx fglrx_* fglrx-amdcccle* fglrx-dev*

You'll may also need to mess with your X11 settings and driver blacklist. Good idea to start keeping track of your system config changes in some kind of log if you're relatively n00bish with Linux.
