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 15.10 and now it only says. No useable GPUs found in the log. WTF?

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?

Open Terminal, copy+paste the following

cd /usr/lib/ && sudo ln -s libOpenCL.so.1 libOpenCL.so


and restart BOINC client.


Maybe one day we'll have a version that doesn't need these workarounds.

I did that. Didnt work.

Did

sudo gedit /etc/default/boinc-client

and added

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 all of the above or the last two fixes that did it, but now it works.

Thx a lot to Juha. This symbolic link helped me to activate my Radeon R9 240A GPU to work under ubuntu 14.04. 312 GFLOPs more for science :-)
Kind Regards,
Horst

Thanks to all for posting these instructions. I want to add that you should create links in the appropriate /usr/lib folder depending on architecture. My 64-bit system eventually recognized the GPU when I did the following:

cd /usr/lib64 && sudo ln -s libOpenCL.so.1 libOpenCL.so

This worked on OpenSuSE Leap 42.1 x86_64, Radeon 7790 and the radeon-crimson-15.11-15.30.1025 driver.
