wrong display size

[Sebastian Gutzwiller]

Hi Ken

Thx for the suggestion.

I made several tries with xrandr. All without success. See also 
https://bugs.freedesktop.org/show_bug.cgi?id=96453

'xrandr --output LVDS1 --fb 640x480' returns 'specified screen 640x480 
not large enough for LVDS1 (1024x768+0+0)'.

There is no visible scroll bar.

Cheers Sebastian
