RE: X resolution (was no-subject)


First of all, your driver will have to support changing to that resolution. The utility you used will appear to let the resolution change go through OK when in reality it doesnt, if the driver doesn't
support it.

The quickest way to make sure the configuration gets changed is to manually edit the /etc/X11/xorg.conf file. If you're using anything previous to Fedora Core 2, then the file will be called /etc/X11/XF86Config.

Under the "Screen" section, there should be Modes listed. Simply insert "1024x768" if its not there already and delete the other ones you don't want. If X won't start after that, then you know your driver doesn't support it ;). You'll probably need a newer or proprietary driver if that occurs, unless its a Optiplex GX270 (you didn't specify what model Dell machine you had).  If its is a GX270 then there's a BIOS bug which reports the wrong amount of video memory to the OS and it won't get anything except 800x600 resolution. If this is the case, update to BIOS version A04 and this will solve the problem.

	      I have installed RedHat in my computer. But my monitor is set to be 800*600 by default. I set it to be 1024*768. The hint told me I should log out and relog in, then the set will take effect. Then I follow the instruction. However it does not change anything.
My computer is DELL, the monitor model is M782.
