Thank you for reporting this bug. That was certainly an interesting behaviour. Could you attach the output of `lspci -vvnn` as well? Does anything change if you move /etc/X11/xorg.conf to a different name and restart? (so that there is no xorg.conf when you start up, there will be a new minimal one created.)
Also, what is your monitor setup? Is this a laptop? Is there an external monitor connected using DVI? If this is not a laptop, you can try the Ignore LVDS Quirk on https://wiki.ubuntu.com/X/Quirks#Ignore%20LVDS%20Output%20Quirk . -- [855gm] entire display shows color of certain pixel https://bugs.launchpad.net/bugs/305269 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
