Comment 26 for bug 587426

I ran across an issue after changing boint to run as my primary user and connecting to the ATI card. I don't recall this behavior when I had it running as "root" but will have to retest that to be sure.

IF you logout the GPU WU running will finish but all subsequent WUs will get repeated errors as below in the WU, the WU will comp out (example from DNETC):

<core_client_version>6.10.58</core_client_version>

Suspending the project (via remote boinc-manager), logging in from remote, and un-suspending the project will allow WUs to process correctly again. So it appears boinc user needs x-session to start and recognize card or to start a WU on the GPU.
