I've just installed Fedora Core 3 on my Toshiba Satellite 2400-103 laptop.
I have three options for my screen resolution: 640x480 800x600 1024x768
I'm trying to have a 1280x1024 screen resolution.
I modified my 'xorg.conf' file and the screen section looks like the following now:
-------------------------------------------------------------------------------------------
Section "Screen"
Identifier "Screen0"
Device "Videocard0"
Monitor "Monitor0"
DefaultDepth 24
SubSection "Display"
Viewport 0 0
Depth 16
Modes "1280x1024" "1024x768" "800x600" "640x480"
EndSubSection
SubSection "Display"
Viewport 0 0
Depth 24
Modes "1280x1024" "1024x768" "800x600" "640x480"
EndSubSection
EndSection
-------------------------------------------------------------------------------------------
However, I cannot seem to be able to select the "1280x1024" option.
It is not displayed neither in: Applications->Preferences->Screen Resolution
nor in: Applications->System Settings->Display

Thanks

Try changing default depth to 16 and increase video ram in the bios to preferably 8 MB.

Thanks makuyl. But my video ram in the bios is already 16 MB.
And changing the default depth to 16 didnt work

Thanks

Well, that was my best bet since I haven't used FC or RH. I usually change the XF86Config-4 manually but I suspect there's some sort of helper in FC for it. In debian you can use kxconfig or xf86config.
