No useable GPU found [Ubuntu 15.10 - AMD R9 280]

[Josef Andersson]

Ive been running Boinc for years on the same hw with Ubuntu and AMD-cards, it has always found the GPUs. I updated from Ubuntu 14.04 to 15.04 and to 15.10 and now it only says. No useable GPUs found in the log.

I verified that I use the latest AMD-drivers from -updates-repository.
I also tried using LotusOfBorgs Boinc-ppa https://launchpad.net/~costamagnagianfranco/+archive/ubuntu/locutusofborg-ppa to see if the problem would disappear with a newer boinc-version, but no.
I read that I might have to restart boinc after login for it to find the GPUs, but it doesnt help.

After some searching I notice A LOT of people seems to be asking about this problem, for many years, and there doesnẗ seem to be a standard solution. How come this can be such a hard bug/problem to solve? Any ideas how I can fix it on my setup?

Hi, I uploaded on the locutusofborg-ppa a few seconds ago the 7.6.19 version, can you please try it?

please also try to use boinc-client-opencl, that should help the client in finding an AMD GPU card.

cheers,

G.

I did that. Didnt work.
I read in some forums,
did
sudo ln -s /usr/lib/libOpenCL.so.1 libOpenCL.so

didnt work

Did

sudo gedit /etc/default/boinc-client

and add

LD_LIBRARY_PATH=/lib64:/usr/lib:/lib:/usr/local/lib
export LD_LIBRARY_PATH

Didnt work.

Did
 xhost local:boinc
and
sudo aticonfig --initial=check

WORK!!

I dont know if it was an combination of the above or the last two fixes that did it, but now it works.
