I had this problem with lucid and had to put radeon.modeset=0 into grub to boot. Later, due to lucid breaking after an update (PS disabling ctrl-alt-backspace in lucid is a bad idea, and even with the radeon.modeset=0, ctrl-alt-f1 showed vertical bars, so I couldn't get to a terminal from there to restart the gnome-panels or nautilus), I did a fresh install without importing any of my old settings and the problem seemed to go away, even though I still had the vertical bar problem with the live cd itself. I can only hope that the problem is solved, because the vertical bars do not always appear on every boot and mostly occur randomly, and I have not had much of a chance to thoroughly test my laptop with many boots.
Using the 2.6.33 kernel completely fixed the problem, but wireless was nonfunctional in that kernel build so I couldn't stick to that. -- [Lucid] ATI KMS causes DRM error on X200M https://bugs.launchpad.net/bugs/509273 You received this bug notification because you are a member of Ubuntu-X, which is a direct subscriber. _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : [email protected] Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
