A couple other details which would help for classifying performance bugs: * If you have a multi-head arrangement, are you using twinview or xinerama (or xrandr for non-nvidia drivers)? * Do you experience it with Unity only, or also Unity 2d? If the issue also occurs with Gnome Shell, that's often well worth mentioning. * Does it *only* occur with gnome-terminal, or also with other programs? * Is the performance trouble continuous from boot, or does it only come on after some time or after some action? E.g. window movement, alt-tab, desktop switching, etc. * When did you first start noticing the performance issue? What ubuntu and driver versions were you using? Since then, what versions have you tested that still had the problem? Performance problems are notoriously hard to track down, so the more you can do to define the problem (and esp. details on how to reproduce it), the easier it is for developers to pinpoint the problem. Finally, it bears repeating that since -nvidia is closed source, there's generally little we can do on the Ubuntu end to help, although sometimes the compiz guys can disable features or take other steps to work around or minimize the problem. But more typically we need to forward the bug report upstream, and we generally only do this for really well written, precisely-defined bug reports, since we don't want to waste their time. ** This bug has been marked a duplicate of bug 877438 Unity/compiz has sluggish performance on dual-head with nvidia driver -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/850649 Title: gnome-terminal extremely slow and display buggy To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-terminal/+bug/850649/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
