I guess the kernel just doesn't like my laptops built in video. With 10.x I
never had this problem but now with 11.x my screen just freezes completely I am
using compiz and the good ol gnome desktop.
Here is the output from my kern.log

When this problem occurs which is every day and seemingly random times I
have gone to tty1 and logged in as root then tried to restart gdm and
kill X but when I go back to my display it is just a black screen I can
hear the sound of the greater go off but no visuals.
