This bug affects me on Ubuntu 14.04 LTS, also tried 15.04. I have two benq gl2450. If i boot with both plugged in, i have performance issues, window drag lag etc... I unplug hdmi one, and plug it in after login, don't have issue, as suggested here, as workaround.
Is it possible that still isn't solved? :( -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1292467 Title: Dual screen greeter can break 3D acceleration To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu-release-notes/+bug/1292467/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
