I did some more test.
The console uses the right resolution: 1280x1024. Only the upper left is used
to display the characters.
When running X the monitor is in the right resolution: 1280x1024. Only

I did some test:
Pressing the menu button of my screen shows the resolution it is running at.
This is 1280x1024 which is as it should be.
In console only the upper left part of the screen is used for the framebuffer
console.
In X the output of xrandr is:
Screen 0: minimum 320 x 200, current 1024 x 768, maximum 4096 x 4096
VGA-0 disconnected (normal left inverted right x axis y axis)
DVI-I-0 connected 1024x768+0+0 (normal left inverted right x axis y axis) 376mm
x 301mm
   1280x1024      60.0 +
   1024x768       75.1*    70.1     60.0
   832x624        74.6
   800x600        72.2     75.0     60.3     56.2
   640x480        72.8     75.0     66.7     60.0
   720x400        70.1
TV-0 connected 1024x768+0+0 (normal left inverted right x axis y axis) 0mm x
0mm
   720x576        50.0 +
   1024x768       50.0*
   800x600        50.0
   720x480        50.0
   640x480        50.0
   400x300       100.0
   320x240       100.0
   320x200       100.0

I definitively have no TV attached to my system.
It seems xrandr is trying to run my monitor and non excistend tv at the same
resolution.

My understanding is:
1. nouveau detects a tv which is not there.
2. the framebuffer doesn't use all screen real estate for some reason.
3. xrandr sets all available screens to the same resolution. There is already a
bugreport about this.
4. as things are now I have to manually change the resolution of my screen.
