I followed the Leigh directions as well as possible. The compiz-check util says okays until it barfs on hardware/setup. More info says I'm running 2624x900 which is too much for compiz. Actually, I've got a 20" 1600x900 monitor running off a docked laptop. The laptop screen is supposedly disabled (lid is closed!) -- and Gnome is just on my 20" monitor, but over in KDE, it still thinks the laptop screen is in the game! I try to disable, but it won't stay dead. Anyway, compiz fusion icon has the same effect the Gnome System/Preferences/Desktop Effects has, namely, it scalps off the window frames and won't let me activate an Emerald theme. Running emerald --replace at command line doesn't seem to effect this problem.
I'm thinking I've got to get the graphics system to really let go of the laptop screen ... but how?
