Just to say that I had the same problem (Dell XPS studio 16, ATI Mobility RADEON). Installing fglrx cured the problem. I have no evidence in my dpkg logs that I ever had this package installed (fglrx-modalias was upgraded with 10.10 though).
-- Upgrading to 10.10RC removed fglrx. After reboot X was not usable (only displaying colored dots and stripes). https://bugs.launchpad.net/bugs/655001 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
