Public bug reported:

Binary package hint: xorg

With a non-existing xorg.conf file, my (Samsung 2443BW) monitor is not
detected properly. Max resolution found is 1600x1200, while it should be
1920x1200.

The mode line is seen in the Xorg.log:
(II) VESA(0): Modeline "1920x1200"x0.0  154.00  1920 1968 2000 2080  1200 1203 1209 1235 +hsync -vsync (74.0 kHz)

But it's not used. Also, although xserver-xorg-video-radeon is
installed, there is no reference to that module being loaded at start.
lshw in turn lists the graphics controller as unclaimed:

           *-display UNCLAIMED
                description: VGA compatible controller

Two problems I think I see are:
- radeon module not being used
- vesa module not using a big enough virtual screen size

Let me know what more info is needed.
