I finally found a solution for this here: https://help.ubuntu.com/community/Metacity
You run "gconftool /apps/metacity". When the window opens, go to General and turn off "compositing_manager". That's it! You won't get the nice drop-shadows around your window borders nor the nice thumbnails, but that's what was making alt-tab so slow on my old Dell Inspirion 6000.https://launchpad.net/~marcus-haslam -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/772177 Title: Alt+Tab "Feels" slow To manage notifications about this bug go to: https://bugs.launchpad.net/hundredpapercuts/+bug/772177/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
