Problem trying to get 1280x960 resolution [solved]

[ianw1974]

Recently, I had a trial version of Red Hat Enterprise Linux ES on my system. It was running 1280x960 no problem.

 

I've since erased the installation, and now have a full version of Red Hat Enterprise Linux AS installed. However, for some reason, I cannot achieve a resolution higher than 1024x768. Everything seems to be configured OK, but I can't get it to go any higher.

 

Here is my xorg.conf, can anyone see anything that is wrong, or anything I can change to get it working again? The monitor is fine, so I'm not sure why it's playing up.

# Then to change the language, change the Layout setting.
# For example, a german layout can be obtained with:

I've actually managed to solve it. The gui configuration utility is pants, and obviously doesn't work.

 

I switched to runlevel 3, and then ran as root "setup". Then chose the xconfigurator option, which then runs a mini X environment to configure the screen resolution. This utility is the same as the gui configuration utility that I was originally using through Applications/System Settings/Display within Gnome.

 

Now, I'm able to run 1600x1200 without any problems whatsoever, so not exactly sure what was going wrong. My xorg.conf looks exactly the same hmmmm.
