Sorry if this has be covered already.
I have had very little luck in having Ubuntu automatically set up
monitors. I often have to edit the /etc/X11/xorg.conf with gedit. I do a
search for the particular monitor that is connected to the PC to find
the horizontal and vertical frequency settings. Then I edit xorg.conf to
look something like this:
"
...
Section "Device"
Identifier "Configured Video Device"
Driver "vesa"
EndSection
Section "Monitor"
Identifier "Configured Monitor"
Horizsync 30-66
Vertrefresh 50-130
EndSection
Section "Screen"
Identifier "Default Screen"
Monitor "Configured Monitor"
Device "Configured Video Device"
Defaultdepth 24
SubSection "Display"
Modes "800x600" "1024x768"
EndSubSection
EndSection
...
"
The above is not from a working file, so yours will be different and may
not need some of the settings. The key here is to find the real data
that matches your monitor and video card capabilities and use those
numbers in your xorg.conf . Make a backup copy of your current xorg.conf
so you can fall back to it if necessary. I have several different
versions saved from different setups. I often crash the X11 screen and
need to Alt-F1 to the command line in order to log in as a super-user to
use sudo vi or sudo pico to edit a bad xorg.conf. Then I
Ctl-Alt-Backspace to reboot X-11 to test the new config file. You may
need to do this several times to get a file that works well.
When I get a working configuration, I write (Sharpie) the monitor data
on a piece of cellophane tape and stick it to the monitor, so I have it
for next time.
