I have found a workarround to use the `mga' driver again: I activated the kernel framebuffer interface in the device section of the X.org configuration file /etc/X11/xorg.conf (Option "UseFBDev" "true").
Section "Device" Identifier "Matrox Graphics, Inc. MGA G200" Driver "mga" BusID "PCI:1:6:0" Option "UseFBDev" "true" Option "OldDmaInit" "True" EndSection I haven't tested it with the default ubuntu kernel, but with my self- compiled 2.6.18-rc6, I had to load the `matroxfb_base' before starting the X-Server. If you compile the matrox framebuffer into the kernel, you shouldn't notice any problems. If you have compiled it as a module, you should add `matroxfb_base' to your /etc/modules file. -- 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
