I am seeing the same problem on my Sony Vaio PCG-TR2 laptop with external VGA monitor. The screen is duplicated at the laptop resolution (1280 x 768) and so only fills the top part of my external LCD display, which has a resolution of 1280x1024. Only one monitor, "Unknown", appears in monitor preferences and I can not change the resolution, as only 1280x768 is available. Hitting detect monitors doesn't help.
The same setup worked fine some time ago when I was running Ubuntu 9.10. I am now running Ubuntu 10.10 -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xorg in ubuntu. https://bugs.launchpad.net/bugs/693417 Title: maverick unknown screen and external monitor not detected _______________________________________________ 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
