Upgrade to Maverick broke the display resolution - Dell Studio
Ok, not sure if I should delete the question. But I am sure some people may face same issue, so I will just answer it anyway.
Disable the additional driver, enable it and then restart, boom, everything back to normal!
Maye to extend Lakshman's post (could someone merge it into his response please): To have resolution properly detected I needed:
- delete xorg.conf (it gets recreated then)
- reboot
- System -> Administration -> Additional drivers; and enable there FGLRX Driver
- reboot
Also try xserver-xorg-video-ati driver instead of fglrx. Fglrx caused problems with display resolution for me when I connected external monitor.
