I ran into an identical traceback on my machine after I installed Kubuntu 64-bit Hardy. In my case, however, I made zero customizations to the out-of-the box drivers or xorg.conf, and my sole graphics card is the integrated X200 that comes with ATI's Xpress200 chipset.
Interestingly, there were no errors in xorg.log, only in kdm.log. (Probably related to the fact that I was getting the login screen, but after I logged in, the screen would go black for a few seconds and I would be kicked back out to the login screen.) Failsafe login worked, and once I disabled the executable bit on displayconfig-restore regular login to the default KDE desktop started working too. (Except that my wide-screen Dell monitor is not recognized and the "Monitor and Display" module in the system settings cannot load.) ** Attachment added: "kdm.log" http://launchpadlibrarian.net/15228229/kdm.log -- [hardy] displayconfig-restore causes X to crash https://bugs.launchpad.net/bugs/202164 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
