Public bug reported:

Binary package hint: xserver-xorg-video-ati

Not sure if this is a bug per se, but here goes.

If I switch to a resolution with a 4:3 aspect ratio(800 x 600, 640 x
480) I see a blank screen. However, this is not the case if I switch to
1024 x 768, which also uses a 4:3 aspect ratio:
