[Cialug] xorg.conf issues

[Tony Bibbs]

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).
