This > session bus will also be running on the XDMCP server. Both hal and dbus daemons are running on both the X server and XDMCP server. And I launch the session with: %head $HOME/.xsession dbus-launch --exit-with-session mwm Still on the XDMCP server I just see: # ps ax | grep dbus 594 ?? Is 0:00.02 /usr/local/bin/dbus-daemon --system 98706 ?? S 0:00.04 dbus-launch --exit-with-session mwm 98709 ?? S 0:00.00 dbus-launch --exit-with-session mwm 98710 ?? Ss 0:00.00 /usr/local/bin/dbus-daemon --fork --print-pid 7 --pri 98712 p0 R+ 0:00.00 grep dbus # and on the X server I just see black screen. I can move the mouse, but nothing happens with any clicks. If I start the session with no dbus-launch, I can use mwm fine, but no dbus. What else can I check? many thanks anton -- Anton Shterenlikht Room 2.6, Queen's Building Mech Eng Dept Bristol University University Walk, Bristol BS8 1TR, UK Tel: +44 (0)117 928 8233 Fax: +44 (0)117 929 4423
