Same problem for me with AMD 64 and ATI Radeon X300 PCIE this while booting from HD ; 2 more comments : (1) funny that this seems to reapear not all the time but each other few reboot ; therefore might be related to a task activated each other few runs like a cron task !? (2) might be related to a bug report of mine (#67728) similar to this one as I got the same black screen when trying either : - to switch session, - or to reboot, - or to halt.
In this latter case after selecting my choice from the KDE session manager It hanged the same way with a black screen with loss of full control ; apparently with new update (of "fglrx" ?) I have not experienced this present again ! My "xorg.conf" file is attached. -- [edgy][regression][rv280] black screen and console freeze when X starts - drm lockup https://launchpad.net/bugs/67487 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
