Trouble installing Compiz as windowmanager for debian
I saw the cool windows effects on the latest revision of Knoppix and wanted to make it a permanent install, since Knoppix is not recommended for a permanent install i went with Debian. I have been trying to install Compiz as the windowmanager. When I run Compiz --replace after i install it i get the following error:
Window manager error: Unable to open X display :0.0
any help or suggestions
Also how do i verify if i changed my default windowmanager from gnome to compiz?
