You can try to edit the xorg.conf including the correct resolution screen.
For safe, first do a backup of original configuration, open terminal and:
Code:
sudo cp /etc/X11/xorg.conf /etc/X11/xorg-backup.conf
Then, edit the screen section of your xorg.conf:
If you are on Xfce, open it with:
Code:
gksu mousepad /etc/X11/xorg.conf
If you are on Gnome:
Code:
gksu gedit /etc/X11/xorg.conf
Now only include the appropriate resolution (below you see an example of my screen section running fine on 1280x1024, if I had the problem you are, I had only to write and keep the resolution I would like).
Example original
Quote:
Section "Screen"
Identifier "Default Screen"
Device "UniChrome Pro IGP"
Monitor "SAMSUNG SyncMaster"
DefaultDepth 24
SubSection "Display"
Modes "1280x1024" "1152x864" "1024x768" "800x600" "640x480"
EndSubSection
EndSection
Example modified
Quote:
Section "Screen"
Identifier "Default Screen"
Device "UniChrome Pro IGP"
Monitor "SAMSUNG SyncMaster"
DefaultDepth 24
SubSection "Display"
Modes "800x480" "640x480"
EndSubSection
EndSection
After you modify the file according your computer specs (not mine, please), save, close it and Quit > Logout.
If not works, you can restore the original configuration with the command:
Code:
sudo cp /etc/X11/xorg-backup.conf /etc/X11/xorg.conf
