I can confirm that I am seeing the same behavior when using a USB DisplayLink monitor and Unity. I upgraded to a mainline kernel of 3.12 to get it working, and see the flashing mouse and slow graphics behavior. uname -a output is:
Linux RJG-Satellite-U945 3.12.0-031200-generic #201311031935 SMP Mon Nov 4 00:36:54 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux I will use apport-collect as requested above to submit details. Thanks. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1213338 Title: Displaylink slow graphic performance on Ubuntu 13 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg-server/+bug/1213338/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
