Interesting. My previous version was 12.04. And I spent a huge time wondering why I'm facing bad performance when enabling the 3D card + external monitor.
Wondering if every people complaining about the poor 3D accel + external monitor get to know about this bug, the size of "affects X people" will increase a lot. -- 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
