To set (or reset) at proper screen resolution Debian (i had the situation where the only resolution available was 680 * 480), it is necessary to reconfigure the xorg.conf file, that you can find on /etc/X11/ directory.
To do that, there are 2 ways: one manually editing the file, and one by using the shell command line. The second more easy and speedy way is:
Open a terminal root.
run the following command: dpkg-reconfigure -phight xserver-xorg
The xserver-xorg window for a new configuration of screen values will be open. Move with arrows up and down and select by clicking space your needed values. I have choose for example to leave setted (and available to the system) 1024*768 and 1280*960).
Automatically xorg.conf file will be updated and you can see your new values inside his code lines like:
Depth 1
Modes "1280x960" "1024x768"
etc etc ...
Launch the Gnome Control Center and choose Screen Resolution. New values are now availables for the screen to be selected.
