I saw in some computers in my lab with graphic card geforce gtx 660 of nvidia and ubuntu 14.04 a weird bug and i'm not sure if that's what that this thread is about. After some minutes of working all or many of the letters in the screen begin to blink or being replaced. I attach a photo of the problem.?
The problem was solved, probably by changing the driver to Nvidia binary driver- version 331.38 from nvidia-331 (proprietary, tested) It seems that changing definitions in compiz did not help ** Attachment added: "picture of the bug" https://bugs.launchpad.net/ubuntu/+source/compiz/+bug/1307144/+attachment/4282850/+files/Screenshot%20from%202014-11-13%2008_19_59.png -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1307144 Title: 'unredirect fullscreen windows' causes tearing To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/compiz/+bug/1307144/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
