I found out another thing when I take a closer look at the Xorg.O.log.

There are the modeline, sync and refresh rates of the monitor, so I think it's only a small step to get full resolution of 1920x1080.
So I played around a little bit based on this post:
http://ubuntuforums.org/showthread.php?t=1843675First I tried in terminal, xrandr -q and get this:xrandr: Failed to get size of gamma for output default
Screen 0: minimum 640 x 480, current 1280 x 1024, maximum 1280 x 1024
default connected 1280x1024+0+0 0mm x 0mm
1280x1024 76.0*
1024x768 76.0
800x600 73.0
640x480 73.0
Then I tried to add new modeline, based on the output of my Xorg.O.log:xrandr --newmode "1920x1080"x0.0 134.60 1920 1936 1968 2020 1080 1085 1095 1111 -hsync +vsync
Another xrandr -q, I get this:xrandr: Failed to get size of gamma for output default
Screen 0: minimum 640 x 480, current 1280 x 1024, maximum 1280 x 1024

v: height 1080 start 1085 end 1095 total 1111 clock 60.0Hz
I get a new screen-size-option !!!
The I tried to add the modeline for the "default" screen:
xrandr --addmode default 1920x1080x0.0
I get output:
xrandr: Failed to get size of gamma for output default
then I tried to "activate" the modeline:
xrandr --output default --mode 1920x1080x0.0
I get:
xrandr: Failed to get size of gamma for output default
xrandr: screen cannot be larger than 1280x1024 (desired size 1920x1080)
Nothing changed at all.... I very disappointed.
I always get this "Failed to get size of gamma for output default" -
What means this ??And after reboot the new modeline (1920x1080) is gone and I have to do the steps again.
And I haven't got the file/directories /etc/gdm/Init/Default (described in the ubuntuforums-Post) to put the options of new modeline somewhere.
But I think we getting closer and closer to teach the system the right monitor options ... please a little help !!!
