Yes, this issue caused a lot of problems with the included window-managers when 14.0 was being finalised.
Here's part of a mail I sent to Pat where I describe what I think is going on:
Quote:
The recent dbus-launch change to xinitrc.blackbox appears to break under XDM with the following error:
XDM authorization key matches an existing client!bt::Display: failed to open display ''
My best guess at what is going on is that dbus-launch connects to the Xserver for whatever nefarious reasons it has but doesn't disconnect before calling exec() on the command specified in it's arguments. When the exec'd window manager later tries to connect to the Xserver it goes "Hang On! I've already got a connection from that process!" and throws a hissy-fit.
The result appears to be that any window manager that is started by a script appears to work when passed as an argument to dbus-launch, but those that are simple executables, such as blackbox and dwm cause the above error and the session terminates. (interestingly, fvwm doesn't appear to suffer this despite being a direct executable - I have no idea why)

That other thread you link to was some of my early attempts at working around the issue, but we quickly found that it worked for some window-managers, but not all.
The following is the approach I use now, which has proven reliable (here at any rate). I don't have openbox installed, but dwm suffered the same issue, and this is how I now resolve it.
xinitrc.dwm:
Code:
#!/bin/sh
# xinitrc.dwm v1.4
startwm='/usr/bin/startdwm --with-dbus'
########################################################################
## Merge in defaults and keymaps ##
########################################################################
userresources=$HOME/.Xresources
usermodmap=$HOME/.Xmodmap
sysresources=/etc/X11/xinit/.Xresources
sysmodmap=/etc/X11/xinit/.Xmodmap
[ -f $sysresources ] && /usr/bin/xrdb -merge $sysresources
[ -f $sysmodmap ] && /usr/bin/xmodmap $sysmodmap
[ -f $userresources ] && /usr/bin/xrdb -merge $userresources
[ -f $usermodmap ] && /usr/bin/xmodmap $usermodmap
########################################################################
## Set background / wallpaper ##
########################################################################
xsetroot -solid grey12
########################################################################
## Start Window Manager ##
########################################################################
if [ -z "$DESKTOP_SESSION" -a -x /usr/bin/ck-launch-session ]; then
exec ck-launch-session $startwm
else
exec $startwm
fi
########################################################################
And then the window manager startup script looks something like this and starts dbus (if requested)
Code:
#!/bin/sh
# startdwm v1.1
########################################################################
## Start DBUS session bus ##
########################################################################
if [ "$1" = '--with-dbus' ]; then
if [ -z "$DBUS_SESSION_BUS_ADDRESS" ]; then
eval `dbus-launch --sh-syntax --exit-with-session`
fi
fi
########################################################################
## Start dwm Window Manager ##
########################################################################
xsetroot -name "$USER ($DISPLAY)"
exec /usr/bin/dwm
########################################################################
Perhaps you can try the same approach with Openbox. |
