Reuben, I agree completely. In some ways Linux desktops today are less responsive than they were many years ago. So let's try and fix it...
First, to confirm if it is a compiz issue, could you please try logging into a "Gnome Classic" session? That uses compiz also, but excludes Unity. To get the Gnome Classic option you will probably have to install package "gnome-shell" and friends. If the problem is compiz then I would really like to fix this. But it sounds unlikely given "the mouse stops moving (it becomes laggy anywhere over 95%), music stops playing, the hard disks stop spinning/seeking (at least audibly)". Those are all hardware/kernel/scheduling issues that are very hard to blame compiz for unless the compiz process is thrashing the CPU or disk. But let's work through the options... ** Changed in: compiz (Ubuntu) Status: New => Incomplete ** Also affects: compiz-core Importance: Undecided Status: New ** Changed in: compiz-core Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/926042 Title: Graphical environment becomes laggy and then freezes under high load To manage notifications about this bug go to: https://bugs.launchpad.net/compiz-core/+bug/926042/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
