Hi Norr,
I have included my Xvnc script in this email.
This version of the script first starts the X server and after that x11vnc.
I have also tried it the other way around but with the same result.
Hope you have a suggestion.
Kind regards,
Harm-Jan

Hi again
My suggestion was to sleep after (not before) you have started your
vnc server .
Please provide your script.

Hi
Thanks for your suggestion but that didn't do the trick.
If I look at the source in session.c I have the impression that a
child process waits for the X display to become available after which
it continues (don't know yet with what).
So putting a sleep before starting x11vnc presumably works the wrong
direction.

Harm-Jan

Hi
I have not tried that kind of setup but I suggest you add a sleep
after you have started your vnc server.
The VNC server maybe requires some time to start.

Dear list,
I am trying to use xrdp with x11vnc instead of Xvnc.
x11vnc was originally developed to provide VNC access to an existing X
session.
However x11vnc can also be used with a virtual framebuffer X session
with Xvfb or Xdummy.
Using xrdp-v0.6.1 I am trying to connect to x11vnc using Xvfb.
Since xrdp starts Xvnc I developed a shell script Xvnc which parses
the
command line and then calls Xvfb and then x11vnc.
When I try to connect to the host running xrdp using Module
'sesman-Xvnc' I do get a connection and in the connection log pane:
connecting to sesman ip 127.0.0.1 port 3350
sesman connect ok
sending login info to session manager, please wait ...
xrdp_mm_process_login_response: login successful for display
started connecting
connecting to 127.0.0.1 5910
error - problem connecting
I then close the log pane and go back to windows and reconnect to the
host using using Module 'console' connecting to port 5910 and the
connection succeeds and everything works fine.
Does anyone have experience in setting this up so I do not have to
connect twice before I have a running xrdp session?
Kind regards,
Harm-Jan Zwinderman
