HOWTO: Set up VNC server with resumable sessions

[jocko_johnson]

I am only able to get the grey X11 screen. can someone please look at my setup and point me in a direction to resolve this?


I am running 10.04, fresh install, all updates current.

Here are my files:

/etc/xinetd.d/Xvnc

service xvnc
{
	disable = no
	socket_type = stream
	protocol = tcp
	wait = no
	user = nobody
	server = /usr/bin/Xvnc4
	server_args = -inetd -desktop xvncDesk -query localhost -geometry 1024x768 -once -depth 16 -fp /usr/share/fonts/X11/misc -SecurityTypes=none
	log_type = SYSLOG daemon info
	log_on_failure = HOST
	log_on_success = PID HOST EXIT
}

service xvncResumable
{
	disable = no
	socket_type = stream
	protocol = tcp
	wait = yes
	user = me
	server = /usr/bin/Xvnc4
	server_args = -inetd :88 -desktop xvnc-resumableDesk -query localhost -geometry 1024x768 -depth 16 -once -fp /usr/share/fonts/X11/misc/ -DisconnectClients=0 -NeverShared passwordFile=/home/me/.vnc/passwd
	log_type = SYSLOG daemon info
	log_on_failure = HOST
	log_on_success = PID HOST EXIT
}

/etc/gdm/custom.conf

[daemon]

[security]
DisallowTCP=false

[xdmcp]
Enable=true
HonorIndirect=false
#following line fixes a problem with login/logout
DisplaysPerHost=2
MaxSessions=16

[greeter]

[chooser]

[debug]
Enable=true

/etc/services
I added these lines

#added by me 10.6.2010 for xvnc server
xvnc		5908/tcp
xvncResumable	5988/tcp

/etc/hosts.allow
I added this line

gdm: localhost

I am testing this locally on the server with the commands:

 Xvnc :4 -query localhost -geometry 1024x768 -once -depth 16 -fp /usr/share/fonts/X11/misc -SecurityTypes=none

and

sudo Xvnc :3 -query localhost -geometry 1024x768 -once -depth 16 -fp /usr/share/fonts/X11/misc -SecurityTypes=none passwordFile=/home/me/.vnc/passwd

as well as trying to connect from a different machine within my LAN and also from my work computer via ssh tunnelling/x11 forwarding ( ssh is configured to allow x11forwarding ).

no matter what the results are the same:

I get the x11 window but I only seethe grey speckled screen with the giant "X" for a cursor - no login window

would really appreciate if someone knows how to fix this.

Hi,

just registered, hope this helps: I had exactly the same setup and the same problem, some of the last updates broke it...
I disabled IPV6 and everything works as expected (saw some strange errors in the gdm logs).

Cheers

[jocko_johnson]

thanks for the suggestion.

sorry if this is a dumb question...

how do you disable IPv6?

edit - found my answer i think:

Just to mention, this is indeed a bug with GDM, listening to ipv6 only:

http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=563406

It is fixed already. For now... disabling ipv6 will do the trick !

Hi, i'm kind of new and didn't want to start a new thread so i ask here. How can i connect to my httpc running win 7 and vnc, from my desktop running ubuntu 10.04. I tried the methods i found on google. None of them worked. I don't want to turn on the tv when i want to make a change in the torrent client, or delete some movies.

Can you also give me a link with a tutorial on connecting to the shared windows drives from ubuntu?

Thanks!!

I have a real head scratcher here..
pretty fresh install of 10.10, and I was trying to set up vnc with resumable sessions, and had originally used this guide:

http://www.stuartellis.eu/articles/vnc-on-linux

But ran into problems - which I'll explain later.
So I assumed the guide was wrong, and instead I followed post #605 (copied exactly the setup, just to get me going)

and then when I tried it, I had the same problem.
The problem is, unless the resolution is set to 640x480, the login hangs.

I created the following screen-shots to illustrate the point -
http://imgur.com/a/tBaSh#QJxD4

one image shows the login correctly (I edited one of the configs to use 640x480)
the second image shows the broken login (this login will not respond to keys or mouse input). The resolution chosen is the only difference between them.

My main desktop is very high res (in case that makes a difference)

could someone please offer any help or advice? using a 640x480 login is really difficult.
I installed vnc4server and xinetd today, so should have the latest versions.

This is my exact same problem. I am running 10.10 and I can't get resumable sessions to run for my life. Same problem when logging into XDMCP or VNC.

An entry in /ETC/HOSTS.ALLOW was required, before that I could not even connect. I have also disable IPV6, but I do not know if that was necessary. Right now at least I have the exact same problem you are describing tails_naf. It works in 640x480, but not in any other resolution.

It was all running nicely in Lucid, after a few tears and lots of sweat. I have had it running since Ubuntu 6.x. But now it seems like it is no more to be.

This probably is a good clue... The greeter has problems. But we knew that.....

Problems are fixed in natty.
A host of new problems introduced, but remote login is back up and working now.

Hi... I am trying to set this up on Natty. I get a blank x windows screen instead of XDMCP. Any ideas? I mean, can you please share your set up to have this working in Natty.
