Ok, spotted the x-window-manager/openbox bug, will fix in grml-live.git. Closing 
now.

No, this call is pretty old actually, so I'm wondering what's going
on... We've to investigate on that.

Yeah, the main design goal has been accomplished.

WRT x-window-manager: is this u-a call new? I could swear I've seen isos with x-
window-manager being set to openbox.

Can this bugreport be closed nowadays, right?

WRT x-window-manager - from grml-live.git/etc/grml/fai/config/scripts/
GRMLBASE/90-update-alternatives:

if [ -r $target/usr/bin/wm-ng ] ; then
   # activate wm-ng only if it is registered as x-window-manager:
   if update-alternatives --list x-window-manager | grep -q wm-ng ; then
     $ROOTCMD update-alternatives --set x-window-manager /usr/bin/wm-ng
   fi

JFTR, the branch mru/x_rewrite contains a new grml-x which does not generate a xorg.conf at 
all. Ch suggested (I'll second that) that we rename the original script to grml-x-legacy. 

I send a patch removing the startx/xinit functions to the grml-etc-core mailinglist as there 
is no longer a need to run grml-x. 

I also suggest that we change x-window-manager to wm-ng, as the new grml-x does not need an 
specific window manager but should start with sane defaults (issue925)

grml-x should provide a way how to start X without generating a /etc/X11/
xorg.conf at all. Actually I've test hardware (ThinkPad W510 with nvidia 
graphics card) where X works OOTB without xorg.conf but fails with grml-x's 
xorg.conf.

I'm not sure whether startup of X without xorg.conf as default is an option for 
us already, though we should start support it as least as an option.
