Hi, I have EXACTLY the same issue as dnprossi with the same symptoms and similar software configuration. There is no way to get to kdm KDE login window, just "black screen" and no activity at all... Ctrl-Atl-Cancel useless... Computer freezes..., just like for dnprossi.
I am using Kubuntu gutsy gibbon with all packages dist-upgraded to the most recent version. Using Linux desktop-pc 2.6.22-10-generic kernel + xserver-xorg v1:7.2-5ubuntu7 + xserver-xorg-core v2:1.3.0.0.dfsg-12ub + xserver-xorg-video-ati v1:6.6.193-1ubuntu1. I am attaching my xorg.conf Regards, Mark Rijckenberg ** Attachment added: "My xorg.conf config using radeon driver that worked until around August 15. After upgrade of ati/radeon driver, the video driver now crashes in Xorg." http://launchpadlibrarian.net/8982189/xorg.confCOMPIZRADEON -- [gutsy] system halts "Black Screen" with xserver-xorg-video-ati.1.6.6.193-1ubuntu1 https://bugs.launchpad.net/bugs/134467 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
