I'm using the latest compiz-git (along with compcomm patches & ccsm) and I'm having troubles with some keybindings. It seems that compiz is somehow intercepting any shortcuts that I try to use that are Control +Alt+*OTHER*. For example, I have set in my xfce keyboard settings to lock the screen on Control+Alt+l, it works fine with xfwm4 and the last version of beryl, but it only sometimes works with compiz. And my set shortcut for xkill (Control+Alt+Escape) doesn't ever work under compiz. The weird thing is that when I press Control+Alt on their own it acts as if that's its own keybinding (cursors disappear etc) but there's nothing set to it (The only thing I could think of is the water plugin, but it's disabled, and the Initiate key is also disabled.) Also if I try and add these shortcuts to the compiz Commands in ccsm it doesn't work either, though others do work (eg Control+Alt+D for show desktop).
