When I come back from standby mode my second display(Viera plasma) won't come out of standby. I have to reboot to get the secondary display back. I have an ati 4850.
I fixed it by going back to 9.4 drivers. Never occurred to me to change drivers I thought driver problems were left with my nvidia card. Judging from this problem and reading around I guess not.
The 9.4 drivers put a shortcut for a WoW trial on my desktop. Bad! And catalyst drivers keep trying to install folding@home. I wouldn't mind so much if that option came unticked by default.
