ati driver 6.7.194 makes GNOME using wrong resolution due to bogus monitor
detection.
There's both a GNOME bug which consider the setting of the wrong monitor but
also, in the first place, an ati driver bug which detects not present monitors
(so root cause of bug #11781 and the like) was *not* fixed.
# with 6.6.3 driver:
$ xrandr
Screen 0: minimum 400 x 300, current 1024 x 768, maximum 1024 x 768
default connected 1024x768+0+0 0mm x 0mm
1024x768 60.0*
800x600 60.0 56.0
640x480 60.0
400x300 60.0
# with 6.7.194 driver:
$ xrandr
Screen 0: minimum 320 x 200, current 1024 x 768, maximum 1152 x 1152
VGA-0 connected 1024x768+0+0 (normal left inverted right x axis y axis) 320mm x
240mm
1024x768 60.0*+
1152x768 54.8
800x600 60.3 56.2
640x480 66.7 69.6 60.0
LVDS connected 800x600+0+0 (normal left inverted right x axis y axis) 0mm x 0mm
800x600 60.3* 60.3
640x480 59.9
None disconnected (normal left inverted right x axis y axis)
GNOME wrongly selects "800x600 60.3*" instead of "1024x768 60.0*+"
but there's actually only a CRT monitor plugged.
This bug exists since at least 6.7.191 but I think it was already there in
6.6.19x
