Hello,

my monitor has a maximun resolution of 1280x1024 but xrandr shows me three
wrong
resolutions:

$ xrandr
Screen 0: minimum 320 x 200, current 1280 x 1024, maximum 1600 x 1200
DVI-1 connected 1280x1024+0+0 (normal left inverted right x axis y axis) 
376mm x 301mm
    1280x1024      60.0*+   75.0     59.9     60.0*

    1280x960       60.0

    720x400        70.1
DVI-0 disconnected (normal left inverted right x axis y axis)

1600x1024 1400x1050 and 1440x900 are not possible. My xorg.conf is very simple
(from a lenny installation last month):

As you can see no 1400x or 1600x resolutions.
xrandr shouldn't display these resolutions because the monitor cannot handle
it.

Thank you.
