As the title states I need to find how to change the resolution in ATI Big Desktop. Both of my monitors should run at 1280x1026 (combined 2560x1026) but instead they are running at 1024x768 (combined 2048x768). I have tried various ways to do it and I cant seem to make them run at 1280x1026. Here is my xorg file -

# xorg.conf (xorg X Window System server configuration file)
#
# This file was generated by dexconf, the Debian X Configuration tool, using
# values from the debconf database.
#
# Edit this file with caution, and see the xorg.conf manual page.
# (Type "man xorg.conf" at the shell prompt.)
#
# This file is automatically updated on xserver-xorg package upgrades *only*
# if it has not been modified since the last upgrade of the xserver-xorg
# package.
#
# If you have edited this file but would like it to be automatically updated
# again, run the following command:
# sudo dpkg-reconfigure -phigh xserver-xorg

I am having the same problem as you.

If it helps, I know my drivers are installed "correctly" and I'm able to get 3D rendering... The resolution will simply not go above 1024x768 (2048x768 ).

Thank you for any help that anyone might be able to provide :).

i had 1920x1200 up and running on two monitors. i can remember i played around a while (even doing stupid stuff like trying ati's catalyst control center...), but in the end the only option i ended up with in my xorg.conf's device section was


Option "EnableMonitor" "tmds1,crt1"
