I was having a problem with video playback not using the whole screen area and discovered it was resolved when I set the display size and DPI's to the correct values. My laptop's detected display size was way off, so getting it set correctly made a big difference.
1. First you can check what X thinks your display size is with the following command:
# sdpyinfo |grep dimensions Output is something like: dimensions: 1152x864 pixels (353x261 millimeters)2. Now measure your monitor in mm and compare the values with the output of the command above. If it's not correct, you'll need to edit "/etc/X11/xorg.conf" and add the following to the "Monitor" Section. (see man xorg.conf for complete details).
DisplaySize width height Where width and height are in mm.3. Restart X by logging out of your GUI session and then hit "CTRL-ALT-BKSP" before logging back in. Then run xdpyinfo again to see if it was corrected.
# sdpyinfo |grep dimensions 4. Now we need to check to see what X calculated the DPI to be. # cat /var/log/Xorg.0.log |grep DPI The output should be something like: DPI set to (value1, value2).5. Now set your GUI DPI resolution to a value within the range of value1 to value2.
On Gnome, you set the DPI in the following location: "System-Preferences-Appearance-Fonts-Details"
6. After you get the DPI set correctly, adjust the various font sizes to suit.
