Same problems with thinkpad X40 since Natty and KDE : This PC have an integrated video Intel i855GM
1- i am now unable to switch screen between internal and external with Fn+F7 2- At boot the external screen is detected but becomes a clone of the internal screen, including taking its size, so I have only a portion of my big external screen that is used 3- if I try to switch with Fn-F7 during Xorg initialisation, before the mouse of Xorg appears, then both screen goes black and are not usable again 4- If I let both screen initialize and kde start, then I am in situation 2, but switch screen hard button is inoperative, and kde monitor settings reports only one screen It is more probably a kernel problem. -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gnome-control-center in Ubuntu. https://bugs.launchpad.net/bugs/766490 Title: [Natty-Beta2] Turning off laptop monitor turn off both monitors (laptop and external) on Vostro 3500 -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
