I hope the attached X.org log files helpes to find the bug in the `mga' driver on Edgy. I used the configuration file attached in the former comment, which was created on Edgy with `dpkg-reconfigure xserver-xorg', but with the same specifications I used for this card on Dapper.
Interestingly, X11and my window manager seem to start, when I run `startx', but the monitor becomes black. ** Attachment added: "X.org 7.1.1 log file on Edgy with MGA200 at 1600x1200" http://librarian.launchpad.net/4213156/Xorg.0.log -- Matrox MGA200 doesn't work after upgrade from Dapper to Edgy https://launchpad.net/bugs/58721 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
