After attempting to resolve that issue by upgrading the Nvidia driver, all went south and the black screen of death ensued. I tested by opening a bunch of videos and running some recursive greps at the same time and found my load actually can get quite close to 8 if I work Even just scrolling down a page in Firefox results in ~70% CPU usage. asked 4 years ago viewed 31575 times active 7 months ago Linked 14 Missing launcher after 12.04 upgrade Related 3Compiz consuming lot of cpu when display is off in 12.043Compiz taking http://1pxcare.com/high-cpu/ubuntu-compiz-cpu-usage.html
