On my laptop I do *not* have this problem. It has the stable NVIDIA driver from the Ubuntu 14.04 repo, 340.96. My laptop has an NVidia Quadro K2000M.
My office computer *does* have the problem. It also runs Ubuntu 14.04 but has the NVidia driver installed with the NVidia CUDA toolkit, 352.63. It has a GeForce GTX Titan X card. I suspect there is some other installation problem with the office computer as sometimes when I ask the computer to "lock" it does not. Probably when 16.04 comes out I will try to reinstall the NVIDIA CUDA toolkit from a fresh install. -- You received this bug notification because you are a member of compiz packagers, which is subscribed to compiz in Ubuntu. https://bugs.launchpad.net/bugs/1292830 Title: Resuming from sleep makes black borders around windows appear To manage notifications about this bug go to: https://bugs.launchpad.net/compiz/+bug/1292830/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~compiz Post to : compiz@lists.launchpad.net Unsubscribe : https://launchpad.net/~compiz More help : https://help.launchpad.net/ListHelp
