vlc makes things crash hard, likely due to my huge playlist. crashes unity and or compiz, sometimes hard enough for one of them to not restart itself. i restart compiz in this case in console with export DISPLAY=:0 , and some functionallity returns. i then ctrl-c compiz from console, and it magically restarted itself and unity to working conditions.
