Seeing the same thing here, on Ubuntu 12.04. Graphics adapter (lspci) is "Advanced Micro Devices [AMD] nee ATI Caicos [Radeon HD 7000 Series]", xserver-xorg-video-ati at "1:6.14.99~git20111219.aacbd629-0ubuntu2".
The "start lightdm" workaround works for me aswell, although I have to *re*-start it, as it claims to be already running. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1070677 Title: Xorg fails to start because of Radeon Issue [(EE) RADEON(0): [drm] failed to set drm interface version] To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-ati/+bug/1070677/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
