[maemo-developers] Can we launch Maemo UI on several Xephyrs from different clients connected to a server?

[From: Kwansu Park]

Hi,
I'm a new comer in this field with maemo.

Actually, I want to launch Maemo UIs onto several Xephyrs.
So I found a thread related to this problem on this mailing list. At that
time, author was Sampath. Maybe the subject of that thread is the same as
mine. :) In the previous thread, there was just one solution about launching
several Xephyrs using a wrapper script(e.g. start-xephyr.sh). There was not
an answer for Maemo UI problems....

Finally, when I try to launch Maeomo UI(af-sb-init.sh start) on each xephyr,
it failed except the first one.
The detail situation of is follows..

 1) I made 2 start-xephyr.sh, it works for each user.
     For a user "kevin"
     #!/bin/sh -e
     prefix=/scratchbox/users/kevin/targets/SDK_X86/usr
     export LD_LIBRARY_PATH=${prefix}/lib; export LD_LIBRARY_PATH
     exec ${prefix}/bin/Xephyr :$1 -host-cursor -screen 800x480x16 -dpi 96
-ac

      For a user "dino"
     #!/bin/sh -e
     prefix=/scratchbox/users/dino/targets/SDK_X86/usr
     export LD_LIBRARY_PATH=${prefix}/lib; export LD_LIBRARY_PATH
     exec ${prefix}/bin/Xephyr :$1 -host-cursor -screen 800x480x16 -dpi 96
-ac


 2) Then, I executed these scripts on the gdm xserver(Ubuntu 6.1 Edgy
distributed)
    root$start-xephyr-kevin.sh 2
    root$start-xephyr-dino.sh 3

     as a result, on the screen, 2 Xephyr launched.

 3) On an other PC, executed terminal program(SecureCRT) and then I logged
in server as other users, kevin and dino.

 4) Then I logged in scratchbox(Apophis (Current stable version)) as each
user.

 5) For the first time, kevin set its DISPLAY, like this
    [sbox-SDK_X86: ~] > export DISPLAY=127.0.0.1:2

    and then another user, dino did the same work except to number of
DISPLAY

    [sbox-SDK_X86: ~] > export DISPLAY=127.0.0.1:3


 6) Then, kevin launched Maemo UI firstly

   [sbox-SDK_X86: ~] > af-sb-init.sh start

    ..........as a result, it worked well, I could find that maemo UI
launched on the xephyr displayed on 2

  7) Lastly, dino launched Maemo UI, like this

   [sbox-SDK_X86: ~] > af-sb-init.sh start

    ..........as a result, it terminated...with that log.

      /usr/bin/af-sb-init.sh: line 1: export: `bus:': not a valid identifier
      /usr/bin/af-sb-init.sh: line 1: export: `/tmp/session_bus_socket:':

 8) Following End.


 Well, I think it might be problem at DBUS sessions and maemo UI
initscript...
 I expected that it'd work well if that problems are fixed...
 Somebody who knows that issue, please, let me know how to fix it...

 Thanks,
 BRs.
