Is this using the stock xorg ati driver, or ATI's firegl driver ? Does it still happen if you set your /etc/X11/xorg.conf to use the vesa driver instead ? It sounds more like an X driver issue than a kernel issue at first impression. If you have this box networked, can you log into it when the display is garbled ? If so, grabbing the X logs from /var/log/ may yield some clues. You have all the Xorg errata installed I assume ? Dave
