Setting the DISPLAY variable to ":0" means to connect to the UNIX
domain socket in /tmp/.X11-unix/X0. You probably can't usefully
copy that socket into the chroot and still have things work. The
easiest way to do what you want is to set DISPLAY to "localhost:0"
(assuming you have localhost's name set up correctly), which will
force an IP domain connection instead of a UNIX domain one.
