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 Desktop Packages, which is subscribed to xorg in Ubuntu. https://bugs.launchpad.net/bugs/1073372 Title: Xorg produces high CPU usage, slow gnome-terminal Status in “cairo” package in Ubuntu: Confirmed Bug description: Thinkpad X220 (Intel video, chipsets, etc) After a few days of uptime and usage on this laptop, the xorg process will start randomly (but consistently over time) producing high CPU usage, even with all applications closed. CPU according to top will vary between about 10% and 90%, and at high CPU times, the system fans will be running rather high. Also, the UIs will slow down and there will be a lot of latency on keypresses (sometimes up to 1 second), with the occasional loss of keypresses. In gnome-terminal, this has the effect of feeling like you're over a cellular modem, even on a local terminal.
