I have the same problem on my computer. The sceen is blank after load of kernel. I have 2 cards on this pc : 1 pci ati and 1 agp : nvidia
Screen was pliugged only on nvidia but xorg was condigured to use ati card. Screen was good in xorg. After edited xorg.conf and replace the device line from ati and nvidia + busid line it worked. Something is wrong in screen detection. -- [regression][rv280] black screen and console freeze when X starts - drm lockup https://bugs.launchpad.net/bugs/67487 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
