I just upgraded to Ubuntu 7.10. Now the screen resolution is stuck at 1600x1200. My monitor is straining to do this resolution and the screen is all bendy. I can't adjust the monitor itself to work with the new resolution as this monitor is shared between three other computers and would need to be readjusted back to the prior settings every time I pressed the KVM switch.
I have been to System > Preferences > Screen Resolution. I pull down the menu and select the resolution which has always worked well, which is 1024x768. I press Apply. The screen resolution *does not change*, but I get a dialog box saying "do you want to keep this resolution or revert to the old resolution?" Selecting "keep this resolution" does not change the resolution to 1024x768.
I've tried Ctrl-Alt-Shift + to change screen resolutions. For some reason 1024x768 is not an option in the list.
I'm presuming that editing a config file is in order. I have no problem doing this and understand the need to back things up. However, I have only done XFree86 config files and don't know what to do with xorg.
Incidentally, 1600x1200 has always been the resolution used by the graphical login screen. I've wanted to change the initial resolution to 1024x768 as well, but I don't know how to do that either. Frankly I just hate graphical login screens, but I can't do without my GUI for normal computer use.
