I have an older Pentium 3 Toshiba laptop that looked fine in Windows XP, and was set to 1024x768. I install Ubuntu now the desktop only uses half of the screen. The video only can be set to 800x600 or 640x480. How can I set it to 1024x768. I googled much information about changing settings in /etc/X11/xorg.conf, but it doesn't matter what I put in there, it seems to be ignored.
What can I do?
The video is Trident Blade 3D by the way
