After I just installed Ubuntu 9.10 64-bit on my dual-monitor (DVI) machine I needed to rotate the display 90 degrees left for my monitor orientation.

The System -> Preferences -> Display option didn't give me the choice of left or right only normal or upside down.

I installed ARandR which provided an easy GUI to configure my xrandr settings. I saved the settings to a file (ARandR created a shell script for me) and added the script to my startup applications (System -> Preferences -> Startup Applications).

Note: When I tested from the live cd my mouse become corrupted. Installing to hard disk did not have the mouse corruption issue.

Also you may want to look in ~/.config/monitors.xml for settings you can modify. After I did some system updates the left/right option appeared under System -> Preferences -> Display again.

http://wiki.gadg3ts.com/index.php/Rotate_gdm_login_screen has great directions. In case it isn't available:
  1. Edit /etc/gdm/Init/Default
  2. At very end before exit 0 add xrandr -o left &
