I've got same problem on COMPAQ S710 (CRT-0) Monitor using GeForce FX 5500 PCI video card.
I'm using Ubuntu 8.10 Intrepid Gnome and KDE 4.2.00
Using System Settings->Display then resize it from 1280x1024 to 1024 x 768, then apply would work. But, when I re log-in it will switch back to previous setting.
Solution: Since I installed restricted drivers in Gnome because I'm using NVidia drivers, I have the application NVIDIA X Server Settings. In Nvidia X Server Settings, I clicked X Server Display Configuration->Resolution->1024 x 768->Apply. Then I would Save To X Configuration File in home folder. Then, I would copy the saved xorg.conf file to /etc/X11, then re-login and it will work.
Comment: It seems that the System Settings->Display won't save the file in xorg as root.
