I've got a Matrox MGA G550 and I've experienced various kinds of X crashes after upgrading to edgy. I've tried all the solutions proposed above and here is the combination that works for me:
- No framebuffer enabled in xorg.conf and no special kernal module loaded (I'm using standard edgy kernel) - Added vga=795 (1280x1024 resolution) in kernel parameters (/boot/grub/menu.lst). Without this it was booting with a very dark screen and the monitor was refusing to display anything after gdm started; - I've upgraded the driver to John's backport above to have 3D (e.g screensaver) working. without this upgrade gnome-screensaver was giving a blank screen before crashing X. Now it seems to work very well and MUCH faster then VESA. Thanks for the tips and I hope this combination may help other G550 users.
