@Zsombor: it really is a hardware problem. You have to turn off AMD's "Cool and quiet" feature that slows down the CPU when it's idle to reduce power consumption. It looks like there is a real problem with the onboard graphics card when the CPU speeds back up again. I was getting white screens under both Linux and Windows until CnQ was turned off.
So either disable powernowd (run 'sudo update-rc.d ondemand disable') or turn off Cool-and-quiet in the BIOS if your laptop has that option. Also, you don't mention your Ubuntu release, but judging by the kernel version, I assume it is Natty. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to the bug report. https://bugs.launchpad.net/bugs/46470 Title: System freeze with white screen To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/46470/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
