I don't think this is a bug. Go to System Settings -> Displays -> Sticky edges
Here I saw that sticky edges was turned "On". Once I turned it "Off" and clicked "Apply", the issue disappeared. Again, this is not an Nvidia issue, as I have the issue with no discrete graphics card at all. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to nvidia-graphics-drivers in Ubuntu. https://bugs.launchpad.net/bugs/990904 Title: Dual monitor problem after upgrade to 12.04 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-control-center/+bug/990904/+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
