I'm having the same problem. Using the free radeon driver, applying the rotation restarts X, always reverting to the no rotation setup.
Using the proprietary fglrx driver, cannot start X having the rotation setup (actually, it freezes the computer when trying to start X -- no CTRL+ALT+Fn, no response from the power button, etc). My card is a Radeon HD 5450 that came with a Dell Optiplex 990. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-ati in Ubuntu. https://bugs.launchpad.net/bugs/683905 Title: Xorg locks up after crash with Radeon HD5670 and dual-monitor setup _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
