Just a note that I get the same white screen with random flashing horizontal line segments on a Gigabyte Radeon HD 4850 1GB (GV-R485MC- 1GH). I didn't see any rainbow patterns, though.
This happens both in Intrepid and the alpha 3 release of Jaunty. Vesa does work, but can't set the resolution of my display, so text gets very blurry. -- cannot start gnome X in intrepid (gray screen with horizontal thin flashing black lines) https://bugs.launchpad.net/bugs/272406 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
