I do not think it has anything to do with ediff, since I do not use that
or emacs.
I have the problem as well, compiz.real going to 103% processor usage
(apparently more than 100 is possible on a dual core). If I ssh into my
laptop then, I can kill all compiz processes, I even have an alias for
it:
alias killcompiz="ps auxf | grep compiz | grep -v grep | awk '{print
\$2}' | xargs kill -9"
And then restart compiz:
/usr/bin/compiz &
And then everything is normal again. Next test: Trying Ctrl-Alt-F1,
typing my username and password blind, and then typing killcompiz blind,
see if I can regain control of my laptop without having to use another
computer.
System specs: Acer Aspire 5920, Geforce 8600 GS 512 MB, nvidia
proprietary driver, Ubuntu 8.04, upgraded from a 7.10 install.
