When I tried to execute your command chromium was using >100% CPU and was unresponsive. It seems that Chromium consumes a lot of CPU too.
But even with no Application running other than Gnome-Terminal Xorg takes up to 10% CPU when I move my mouse. Now while I'm writing this chromium is running fine but sometimes it just slows everything down. And my systems is very slow even with chromium closed. chrissi@hansi:~$ apport-collect 1101999 Package xorg not installed and no hook available, ignoring -- 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/1101999 Title: After updates xorg consumes a lot of CPU when doing anything Status in “xorg” package in Ubuntu: Incomplete Bug description: I did a fresh install of 12.04 a couple of moth ago. Everything worked fine. I did the usual update via update-manager 2 days or so ago, were xorg packages were updated. Now when I do _anything_ xorg consumes between 40% and 60% CPU and the whole system is very slow and laggy. This happened after the reboot I did after updating. Maybe theres a connection?
