Hi. I report the exact same problem described by Hubert. I have a Dell L501x with Nvidia 435m. I'm using nvidia-current 275.19-0ubuntu1~natty~xup1 from x-updates.
One fix for this problem is to disable RandR in xorg.conf (Adding Option "RandR" "0"), but this is inconvenient for several reasons. Btw, thanks for the resolution change tip. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/751047 Title: Screen flickers at random times with nvidia 270.30 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/nvidia-graphics-drivers/+bug/751047/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
