I've decided to give it a proper go this time and as it's still not detecting my GPU I thought I'd pop in here for some advice. Ubuntu 11.04 64 bit BOINC 6.10.59 (from Ubuntu repos) ATI FGLRX 11.5 driver Is there anything I need to do above and beyond installing the application in order to get the GPU to work? ID: 38360 ·

For some reason the tasks that look to be GPU ones (usually with ATI in the name) seem to be finishing after about 7 seconds with no output file no matter which project I use. ID: 38394 ·

If it's which projects I tried, it was Collatz, Moo! and PrimeGrid. I couldn't see how the issue could be project-specific when it affects me for all the ATI Linux 64-bit projects. ID: 38397 ·

I'm running the latest proprietary driver from AMD for an ATI Mobility Radeon HD 4500 Series. It's reporting 512MB of VRAM and BOINC is detecting my GPU. Apparently the shader in the card has 128-bit precision, which I think is the part you are asking about? Some projects just say they don't have GPU workloads for me, while others complete in about 7 seconds with no output file, yet hardware acceleration works fine outside BOINC. ID: 38464 ·

Please go for 6.12.26+ which is most likely available from https://launchpad.net/~pkg-boinc/+archive/ppa (just checked, 6.12.18 seems to be the lastest one, anyway). Maybe you can install 6.12.33 from the Oneiric Ocelot? https://launchpad.net/ubuntu/+source/boinc For some mysterious reason, the regular Linux BOINC packages are still with 6.10.58. 6.12.33 is working just fine for me - not having tested the GPU support.
