changing screen res to 12801024

Hi all,

I am trying to change my screen res from 1024x768 to 12801024 and can't seem to work out how to do it.

I have tried to update the refresh rate but it won't let me as the options are not available.

My monitor and gfx card will support said mode but for the life of me I can't work out how to do it.

It is a swine when I can write a program in ASM to do it but can't work out how to do it though the OS.

Not a hard problem to solve but either due to user ineptitude or alcohol I need a pointer in the right direction towards a resource that can help me.

Thanks in advance.

Here's a shot in the dark.

Take a look at /etc/X11/XF86Config. (It's there on Slackware; it might be elsewhere on Fedora.) You probably have something like:

    Subsection "Display"
        Depth 16
        Modes "1024x768"
Change that to "1280x1024", and you should be all set.

In fact, mine is this:

    Subsection "Display"
        Depth 16
        Modes "1280x1024" "1024x768" "800x600" "640x480"
I do this so that if I want to take a closer look at something on the screen, I do a <Ctrl><Alt><keypad-plus> to zoom in progressively, and <Ctrl><Alt><keypad-minus> to zoom out. It circulates, so if you're at 1280x1024 and do a <Ctrl><Alt><keypad-minus>, you'll go immediately to the most extreme zoom.

At least it works that way for me.

Hope this helps.

You could run the command system-config-display as root.
