How should I start a VNC session at boot time in Jaunty?

Asked by Martin Jackson

I would like to start a VNC at boot time in Jaunty. In Intrepid, I used an rc.local script to do this. In Jaunty, the VNC program runs, but the X session it starts hangs at the X startup screen. I have tried this with vnc4server, tightvncserver, i915 and nvidia-180 (all on the same machine!).

When I ssh to the console (i.e. with putty, as a normal user) I can start the vnc session fine. When I try to run the same command from a gnome-terminal inside an X session started by GDM, I get the same results as I do from starting at the boot script.

Does anyone have advice?

Thanks in advance. :)

I think you should find and port the error output, the log for information. What error do you get when you start it from terminal?

OK, starting from within X (which fails):

When starting from rc.local, this is as far as the tightvnc server process gets:

There is a thread about this (although it is old), some file paths are old and wrong

http://ubuntuforums.org/showthread.php?t=488207

In this thread, there is a section called adding vnc to gdm startup. You can add the suggested line to:

/etc/gdm/Init/Default

file. The line is:

/usr/bin/x11vnc -rfbauth /etc/x11vnc.pass -o /tmp/x11vnc.log -forever -bg -rfbport 5900 -xrandr

--I think you have to modify this line according to your needs (port number, etc.). And change the lines in /etc/gdm/gdm.conf like:

#KillInitClients=true

And change it to this:

KillInitClients=false

--I am not sure that this is the information you need, but this may help you figure out the problem about gnome-session.

Yes, I've done x11vnc. It conflicts a bit with the native X settings. But this is a good reminder. If I get to wits end I'll try it but I'm hoping for a better answer. :)

FYI - I'm using the x11vnc from GDM solution for the moment. It seems to be working well enough.
