Following up on rmcd's comment: neither of my monitors is rotated, and I still have issues with the proprietary nvidia drivers.
I am now running on the open source nouveau drivers. They have a couple other glitches (I can watch flash videos only on the leftmost monitor!), but no slowdown over time. Overall much more acceptable. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1011698 Title: Performance problems with Nvidia driver To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/nvidia-graphics-drivers/+bug/1011698/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
