I've been using the xserver-xorg-video-mga_1.4.4.dfsg.1-1jdong1~6.10prevu1_i386.deb driver for a while now with a g400. I've had some random X crashes, most noticeably with gnome-screensaver. I have also noticed that some of the 3D animations render incorrectly. For example the 'Engine' screensaver appears to render out of order having hidden parts showing where they should not.
The 3D animations in xscreensaver seem to work fine so far. The initial boot, which I'm assuming is a vesa driver, is still very dark. -- Edgy upgrade breaks multiple Matrox cards https://launchpad.net/bugs/58721 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
