when trying to fix broken packages, got this message in terminal window:

GConf Error: Configuration server couldn't be contacted: D-BUS error: Can't overwrite existing read-only value: Value for `/apps/metacity/global_keybindings/panel_main_menu' set in a read-only source at the front of your configuration path

has this to do with unity crash??

I also re-enabled unity plugins in ccsm, but I keep getting black screen and unresponsive windows(terminal comes up but I cannot type commands)
when I reboot, 2D version works but seems rather slow.
