Problems with Screen Resolution

[Kishore]

This kind of questions should really go to your distributions mailing list. :)

Anyway, for any useful replies you must mention what hardware (graphics card) you are working with. With intel cards (and maybe others), the `xrandr` command at the CLI should list all supported resolutions for the display/graphics card combo.

When I upgraded to Fedora 12, I had similar problems getting the resolution to 1280x1024, I had to use system-config-display and create an xorg.conf file and add nomodeset to my kernel boot line in grub to get it to work.
