@ericw: I tried the two things you suggested and they both worked! - I set the BIOS AGP speed from 8x to 4x. I can then boot the Live-CD without any "tricks" ... I did not need safe graphics mode nor any boot parameters, no editing of xorg.conf, either.
(For Daniel Moyne: In my BIOS it's under "Advanced" - "Chip settings" ... check out yours, you'll probably find the setting.) - I set the AGP speed back to 8x for testing. I then only commented out the module "dri", not "glx". That was sufficient, as ericw suggested. -- [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
