OK, so kernel 3.2.0-030200rc1 seems to consistently behave like this: * boot up an x201 docked with dp connected to an external monitor * grub appears on both screens * plymouth appears on both screens * lightdm appears on both screens in low-res mirrored mode * unity session comes up with both screens blank * fn-f7 can get it back to mirrored mode * trying to switch to the external monitor does not work
What does work is, from the displays panel: * turn on both in mirrored mode * then turn off mirrored mode, but leave the external panel at a low resolution * set it to 1920x1440, and apply * then change to 2560x1600 and apply so there is some path-dependency: full resolution will only work if you previously set it to a lower resolution. i hope that helps. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-intel in Ubuntu. https://bugs.launchpad.net/bugs/745112 Title: [arrandale] desktop is messed up with external monitors (x86_64) To manage notifications about this bug go to: https://bugs.launchpad.net/xserver-xorg-video-intel/+bug/745112/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : [email protected] Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
