Annoyance I've noted on 7.0.x incl 7.0.4 on some nvidia cards 7800 and 8800 maybe more systems is repetitived blanking of the screen (ie, 10-15secons On, 2 Seconds Blanked Off) dont think it related to what I've read (nvidia driver / compis usage / powerthrottle on card mhz speed change) but for a workaround to not using the no3d cheat code on the kernel command line append drm_kms_helper.poll=0 Will stop screen flickering but I think problems is still there.
