BOINC fails to detect the GPU of the AMD A4-5300 APU.

With the OpenCL drivers and the latest AMD SDK installed it detects the CPU as OpenCL-capable, but not the GPU.

There are various articles on the BOINC forums, and the various projects' forums, all giving advice that doesn't help, but this should really work out of the box. I am unable to get this to work at all.

Also tried with 7.4.23 from PPA https://launchpad.net/~costamagnagianfranco/+archive/ubuntu/boinc

Irritatingly it did work ONCE running 7.4.22 (from the BOINC website) as the logged in user, but I have no idea why or how to recreate this. I tried setting "xhost +" too but this had no effect.

ubuntu-bug refuses to report this bug.
