Comment 7 for bug 513890

Suspend/resume is unsupported when using the -vesa drivers, which some nVidia cards fall back to because -nv drivers don't work with all nVidia chips. I don't know the status of -nv driver resume, but it may not be good either. However, -nvidia driver resume should work.

I have marked this bug as a duplicate of another pm-utils bug that is tracking an upstream fix. You can find a workaround for this issue there. If the duplicated bug does not fix your problems, please open a separate bug with your symptoms (after looking for similar bugs already submitted of course).

Thanks
