Regarding xorg.conf on my hard disk, which has Ubuntu 10.10 - I renamed it so as to have no file with exactly that name, but the problem persists in 10.10, as it does with a live CD for natty.
Regarding Xorg.0.log - no, it does not grow as the screen goes blank. ** Changed in: xserver-xorg-video-intel (Ubuntu) Status: Incomplete => New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/681054 Title: screen repeatedly goes black for a fraction of a second -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
