(screen wraps right and down by one pixel when you switch from 640x480 to 320x200 mode) It does cause problems, though, when I switch from full screen mode (i.e., the X server is 640x480) back to 1280x1024. To recap: I've got a Matrox Millennium with 8MB RAM. I run at 1280x1024@32bpp with XFree86 3.3.3.1.
