Note: Corrected a typo: sdpyinfo should be "xdpyinfo"
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:
# xdpyinfo |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.
# xdpyinfo |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.

Thanks Lee, I wasn't having a prob but i like to try all of the good
tips you post and got 'no such proggy' message but now get:
herb@Celf:~$ xdpyinfo |grep dimensions
dimensions: 1152x864 pixels (381x278 millimeters)
herb@Celf:~$
I find doing these CLI commands helps a lot in the basic understanding
of how the Linux sys works.
COOLNESS
neat stuff thanks
herb
