Bug 13229 was marked as a duplicate of this one, and still affects ati master.

The problem arises because VGA output is now enabled by default even if
no external monitor is attached, and for some reason for me it has a resolution
of 1152x768 (not 1024x768). So, it's as if I'm using an external monitor
that's slightly bigger than the laptop screen, and the mouse carries on
past the right-hand edge of the display.

With metacity, windows still maximise to the correct size (but Fitts'
law is broken), and with simpler window managers (e.g. evilwm) the
windows maximise to the size of the virtual screen.

I should note that "xrandr --output VGA-0 --off" does fix the issue for me
until restarting X, but I expect quite a few people will notice this bug and
won't want to edit xorg.conf.

My logs and config files are at http://bugs.debian.org/458415 .
