Maybe you could try a newer driver. NVIDIA has fixed performance problems with geforce 8xxx and Compiz.
Both of you, please follow these steps: 1) enable the hardy-updates and the hardy-proposed, universe and multiverse repositories and refresh your list of packages. 2) install envyng-gtk 3) launch envyng from the Applications/System tools/EnvyNG menu and select the automatic installation. Follow the instructions and see if (after a reboot) you notice any difference. 4) disable the hardy-proposed repository. -- "separated X screen" in NVIDIA Settings + Compiz = all GNOME and Gtk Apps menus appear too slowly https://bugs.launchpad.net/bugs/234963 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
