I've got the same issue, where I will try to restart X and it will black out with the blinking cursor.
However, I have an Intel GMA 950 using the i810 driver. Please also note I am using Ubuntu 6.10 x86-64. -- [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
