"can't connect to X Server"

Inzwischen hab' ich noch mal versucht das chroot-X-Server-Problem zu lösen. Bisher leider ohne Erfolg, denn ich krieg' immer noch "Cannot connect to X Server :0", trotz:

Code:
xhost + local:
chroot
export DISPLAY=:0


Weiß jemand Rat?

um in chroot x und kde zu haben, mache ich in chroot

cannot connect to X server :1
