Display restricted to 640x480

Asked by DanBehiels

I have recently installed Ubuntu 6.06 and with the default setup, I am unable to set my screen resolution to anything above 640x480. I edited the xorg.conf file to set modes available for my hardware "1024x768" "800x600" only. It appears as though the system defaults to 640x480 when I get the to login screen, but i am a little bit new to linux and am unsure of how to check error logs.

The system does recognize my hardware : noted below. Solution in item: Screen Resolution was not successful.

Device: 82845G/GL[Brookdale-G]/GE Chipset

well, you could try using the vesa driver, see if that's where the problem lies:
edit /etc/X11/xorg.conf
the part with:
Section "Device"
  Identifier "my graphics card"
  Driver "vesa" # <--this is the line you need to edit

If I understand correctly, you've already got everything fine here:

Section "Screen"
  ....
  DefaultDepth 24
  ....
 SubSection "Display"
                Depth 24
                Modes "1024x768" "800x600" "640x480"
        EndSubSection

hope this helps!

I had same problem and could not resolve. So I switched Monitors from a 17" that was 5 years old to a newer one that was 2 years old and was able to go in and change resolution to 1024X768.
Perhaps you could experiment with a different monitor and see if it will work for you! Good Luck: Dick

You could try to launch this command:
sudo dpkg-reconfigure xserver-xorg
Follow the wizard and launch dexconf when finished. Now you're ready to restart X.
See https://wiki.ubuntu.com/FixVideoResolutionHowto for additional tricks.

Looks like your X.Org display configuration is wrong. Try setting refresh rates in your X.org configuration manually.

Can you help with this problem?
