The bug you're describing appears to be different, I don't even run empathy. telepathy-indicator and /usr/lib/telepathy/mission-control-5 are running, but produce no load.
I did track down what appears to be my problem. Most of my problems happened when dealing with gnome-terminal, particularly when there's a lot of scrolling text. This bug appears to be relevant, though I have an Intel display, not Nvidia: https://bugs.freedesktop.org/show_bug.cgi?id=48395 Upgrading libcairo2 and libcairo-gobject2 to the version in raring (1.12.8-0ubuntu4) seems to fix the issue, and this was not present in precise, so I believe there's something in Cairo 1.12.2-1ubuntu2.1 (quantal). ** Bug watch added: freedesktop.org Bugzilla #48395 https://bugs.freedesktop.org/show_bug.cgi?id=48395 ** Package changed: xorg (Ubuntu) => cairo (Ubuntu) ** Summary changed: - Xorg produces high CPU usage after a few days + Xorg produces high CPU usage, slow gnome-terminal -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xorg in Ubuntu. https://bugs.launchpad.net/bugs/1073372 Title: Xorg produces high CPU usage, slow gnome-terminal To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/cairo/+bug/1073372/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : [email protected] Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
