I've made a breakthrough in understanding this problem. It seems to give
me a 100% workaround but of course I can't be sure.
The solution is to use "taskset" to force the "Xorg" and "compiz"
processes to always be run on the same CPU. The simple terminal commands
are:
taskset -pa 1 $(pgrep -
I have now installed the nVidia proprietary driver and hopefully it will

I have also entered a bug in the bugzilla at freedesktop.org. This bug
is number 58594. I was advised in response to that bug that many changes

My Hardware is HP Mini 110. It appears that it only works properly using
800x600 for the external monitor, but I can use native 1024x600 for the
internal screen.
After a few minutes it freezes up in such a w
