After days lost with replacing NVidia drivers and manually editing xorg.conf file, I finally found this!
Rockwalrus (rockwalrus) solution works! On CompizConfig Settings Manager, go to "General Options", then "Display Settings" and do the following: - Uncheck "Deteck Outputs" - In the Outputs array, set the resolutions of each of your screens. The numbers after the resolution "1920x1080+0+0" are the offset. It's important to add this offset according to your needs. I have two full HD screens, so I added the following configuration: 1920x1080+0+0 1920x1080+1920+0 The second output has an offset of 1920, because it is on the right side of the first output, which has a width of 1920. I was hopeless already, what a relief! -- 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/1382462 Title: 10de:0dfa Desktop/windows painted incorrectly in dual monitor configuration To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1382462/+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
