Comment 1 for bug 1172851

I tested this, running the script manually works:

/usr/share/checkbox/scripts/gpu_test

but running through plainbox doesn't:

plainbox run -i suspend/gpu_lockup_after_suspend

plainbox is smart enough to run the dependencies first (suspend_advanced_auto), after suspending and resuming it invokes the lockup test and produces the error seen above.

Note that the job is defined to run as root, this may have something to do with it, however I remember it running OK from within checkbox.
