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.
