Public bug reported:
Binary package hint: xserver-xorg-video-ati
Intrepid only offers me only the native resolution of the display
(1280x786). However, for presentation purposes, I would want to be able
to go to 1024x786 or 800x600. These resolutions are offered for the
display on VGA-out, but if I select them, I only get a subset of the
entire screen.
$ xrandr
Screen 0: minimum 320 x 200, current 1280 x 768, maximum 2080 x 768
VGA-0 connected (normal left inverted right x axis y axis)
1360x768 59.8
1024x768 60.0
800x600 60.3
640x480 59.9
LVDS connected 1280x768+0+0 (normal left inverted right x axis y axis) 0mm x 0mm
1280x768 60.0*+
S-video disconnected (normal left inverted right x axis y axis)
FGLRX driver allows me to change resolution of my laptop screen to lower
resolutions.
Similarly to other bug reports and the solution to them I tried the
following, with no luck:
Option "UseFBDev" "true"
Option "IgnoreEDID" "true"
