|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.
