I sent this last Monday but never saw it show up on the list so I
apologize if it is appearing for a second time:

I have a laptop that can do 1400x1050 and use that most of the time;
however, when I need to hook it up to a projector at work, I change
the resolution to 1024x768 since that is all the projector can handle.
With Red Hat 8.0 this worked, but now with Red Hat 9, the only two
options I have are 1400x1050 and 1280x1024. The ctrl-alt-(keypad+)
only switches between those two. xrandr -q only lists those two.
When I use redhat-config-xfree86 to configure the display as a
1024x768 generic lcd, I get:

What happens if you leave the reqular 1400x1050 configuration, then edit /etc/X11/XFree86 so "1024x768" is listed along with "1400x1050" and "1280x1024" ? can you switch to 1024 mode then?


What's in /var/log/Xfree86.0.log ?

What chip/driver is used? Does the driver haave any tuning variable for the CRT output that might have changed defaults?

I had to play with my C&T card setting to get a workable display. It defaulkted to stretch mode for 640x480, and was horrid, tweaking the options fixed that, and I get 640x800 center on the screen, unstreched.
