I re-installed Dapper from CD on my laptop that was experiencing this bug. The bug has now disappeared. In my case at least ubuntu seems to have special-cased my laptop all on its own. I installed from a boot of the live session in safe graphics mode, as normal mode failed to boot due to this very bug. After installation, it has set my video driver in xorg.conf to "vesa" rather than to "savage" as the previous install did. I'm pretty sure the previous install was an install from CD, not an upgrade to breezy. So I don't know what caused the change in driver choice, unless maybe it was the safe graphics live session, but to be honest, I think I was probably using that last time too. It's a mystery.
Anyway, I can confirm that switching Driver="savage" to Driver="vesa" in xorg.conf appears to fix the problem. At least, I haven't seen it in two days since I re-installed. -- X.org does not initialize screen on IBM T20, T21, T22 https://launchpad.net/bugs/33617 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
