I have build a Linux box out of old bits. One of them being an old Dell (Sony Trinitron) 15" monitor. My first venture into Linux was Mandrake which only allowed me to select 800x600 resolution. I found there was a utility before X loaded that would allow me to use 1024x768. I now run Fedora 3 and am pleased with it, however, it only allows 800x600 with no facility to change to the higher resolution. I have "played" with the xorg file but had no success to date other than forcing the monitor out of syc and having to use init 3 to get it back.

Is there some other facility in Fedora that will allow me to change the resolution?

I use slackware so I dont know alot about FC or RH, i know in slackware there is a utility but it only allows you to choose between resolutions that are in xorg.conf, i think that you need to use xorg.conf, check your vert and horizontal refresh rates. try edit it again.
good luck
