The VGA driver only supports 640x480 with 16 colors, so you can't have been running the VGA driver, which brings up the question of what you actually are running. > > This is a little limiting :-) > > So I suspect my problem is rather deep rooted. > > I have run Mandrake 9.0, 9.1, 9.2 and 10.1 successfully > on this machine; this is the first graphics > problem I've had. > > Any hints (as always...) gratefully accepted. The "broken display" snapshot you showed looked like a rendering problem (like pixmaps were blitted to the wrong place). That can't still be happening with Option "noaccel" or it's an application issue, not a server issue. You need to send us your /var/log/XFree86.0.log file so we can see what you're really running.
