This almost works perfectly. I was in 1280x1024 but I noticed for that
to work it was using the vesa driver. Now I have no problem with using
vesa if I can get it to work. The problem now is that moving windows or
scrolling causes the screen to redraw. Are there options that might
help eliminate this?
On a different note, when the lease is up on this laptop I will go
through great lengths to avoid ATI. Now if I could only get someone to
explain why this laptop is on a long, four year lease (sigh).
