BIOS was upgraded: $ sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date 8BET62WW (1.42 ) 07/26/2013
However, that did not change anything. With 331.113 the same problem exists. I have also made tests with docking station and two external displays. The results: 1. LightDM login screen is OK 2. Dual monitors from docking station with laptop screen turned off: OK 3. Three monitors from docking station with laptop screen turned on: FAIL Laptop screen is turned on, but is black. Cursor can be seen on it, i.e. mouse can move to laptop screen, but windows cannot be dragged and icons (i.e. X desktop begins at) are on second display. Screenshot is also attached. 4. Reverted to 331.38: three monitor setup is OK. Attachments will follow. ** Attachment added: "01-LightDM-looks-OK.jpg" https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1401434/+attachment/4281454/+files/01-LightDM-looks-OK.jpg -- 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/1401434 Title: Desktop is distorted after update to 331.113 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1401434/+subscriptions _______________________________________________ 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
