ATI Catalyst screen resolution does not stay set in Ubuntu 9.10

Every time I reboot, my screen resolution gets set to 1280x800, 1/4 of the 2560x1600 I like on a 30 inch monitor. All of my icons get moved and it is annoying.

I tracked down the amdcccle file which launches the `catalyst control center`, but there is no data file associated with it.

The system -> control_center -> display does not stick either. Does anybody know how to make the settings permanent?

Ubuntu 9.10 x86_64, latest catalyst from ati.

Thank you,

Type in as root "aticonfig --resolution=0,2560x1600".Remember to do it as sudo this way the xorg,conf can be written to. If this does not work check the permissions to that file.

Sometimes you have to remove the saved ATI options.

# rm /etc/ati/amdpcsdb

(but keep the amdpcsdb.default file)

Baring that check your xorg.conf. The first mode listed for the DefaultDepth color space is the one that will likely be the default when you start X. You could also setup a virtual space for your desired resolution. It might not prevent it from starting in a low resolution, but it should prevent your icons and such from shifting.

# nano /etc/X11/xorg.conf

You might also check your logs to see what is happening when.

$ less /var/log/Xorg.0.log

NOTE: # means as root, but since you're running ubuntu that will likely imply some form of sudo.
