[openbox] cannot get Openbox to start on Ubuntu 9.04

[Schild, ChristianHelge]

Hello,

I installed Ubuntu 9.04 as a minimal system without a GUI. Then I added via aptitude the packages xorg (v1:7.4~5ubuntu18), openbox (3.4.7.2-3), openbox-themes (1.0.2), obconf (2.0.3-build1) und obmenu (1.0-1ubuntu1).

When I try to start Openbox from the commandline via openbox-session I get the error messages:

xsetroot: unable to oprn display ''
Openbox-Message: Couldn't set locale from environment.
Openbox-Message: Failed to open the display from the Display environment variable.

I then created a .xinitrd:

#!/bin/bash
exec openbox

and tried to use startx. That just gives me a black screen with a mouse arrow in the middle which is however not moving.

Has anybody a clue what is wrong here? The XServer or Openbox?

Thanks for any help,
Chris
