VNC broken after upgrading with ubuntu 11.10

**Macau Pav** · 31-03-2012

Recently I have upgraded to ubuntu 11.10 32 bit from 11.10. after doing that I have noticed that VNC server does not starting automatically. On the Desktop Sharing panel anyone can view as well as control the desktop and even there is no need to enter password as well.
When I tried to execute vino-server through the command line and got ‘vino-server 2464 WARNING: The desktop sharing service is not enabled, so it should not be run.’
Can you tell me how can I resolve the above mentioned problem?

I got something which can help you out to understand the entire thing. the VNC (vino-server) is starting only when I am using gnome. In perviosu vesion of ubuntu I was using Gnome and in current version I am using Unity. I installed gnome-fallback package and logged into the same so that I can make use of it. after that VNC started to work flawlessly on my computer.

If you have already install Gnome on your computer then you will need to change the default session to the Gnome classic by using following code.

Code:

sudo /usr/lib/lightdm/lightdm-set-defaults -s gnome-classic

now restart your computer and see whether it makes any difference in the situation.

I was suffering from the same issue which you have stated over here. but I resolved the issue by simply installing x11vnc. As Unity and Gnome3 are use accelerated. According to me compositing client will not be able to use or see remote desktop by using Vino. x11vnc is having support for framebuffers and it is transmitting actual video which X has been showing on remote screen and that’s why it is working well. You will need to create small script and simply place the same at a startup folder. I know its not so easy to setup Vino.

Well I have done little bit research work and found following thing to do.
First of all you have to execute below mentioned command on Terminal.

Code:

apt-get install tightvncserver

after that simply add below mentioned line to /etc/lightdm/lightdm.conf

Code:

[VNCServer]
enabled=true

finally you have to restart lightdm.
Once you have finish with above mentioned steps you have to log into VNC and there wont be any issue

Yes Vino is broken after upgrading to ubuntu 11.10 but one will be able to fix it by using below mentioned steps.
First of all you have to installed x11vnc by using

Code:

apt-get install x11vnc

once done you have to create /etc/init/x11vnc.conf file

Code:

start on login-session-start
script
x11vnc -xkb -noxrecord -noxfixes -noxdamage -display :0 -auth /var/run/lightdm/root/:0 -forever -bg -o /var/log/x11vnc.log
end script

now restart you computer and x11vnc would begin to listen on vnc startard port – 5900.

The above mentioned script is based on upstart event mechanism. Lightdm is triggering login-session-start event and you can get the same into lightdm.conf. now you have to start x11vnc it triggers the event.

I hope below mentioned fix would work for you.

Uninstall all the VNC packages including vino / vinagre.
You can use below mentioned command.
Code:
```
sudo apt-get remove vino vinagre -y
```
sudo apt-get autoremove –y

Give a try to below mentioned steps and tell me about your experience.

Install vnc4server by using below mentioned steps.
sudo apt-get install vnc4server
after that you have to install gdm and gnome-panel. It will install gnome-classic.sessions session file at usr/share/gnome-session/sessions/

Code:

sudo apt-get install gdm

when it prompts for default session manager you have to select lightdm

Code:

sudo apt-get install gnome-panel

when it would launch vnc4server very first time you have to set password.

Code:

/home/<user>/.vnc/xstartup

After that you have to change contents of /home/<user-name>/.vnc/xstartup file so that you can make the thing working for you.
Content should be displayed something like below

Code:

#!/bin/sh
# Uncomment the following two lines for normal desktop:
unset SESSION_MANAGER
unset DBUS_SESSION_BUS_ADDRESS
#exec /etc/X11/xinit/xinitrc
#. /etc/X11/xinit/xinitrc
gnome-session --session=gnome-classic &
[ -x /etc/vnc/xstartup ] && exec /etc/vnc/xstartup
[ -r $HOME/.Xresources ] && xrdb $HOME/.Xresources
xsetroot -solid grey
vncconfig -iconic &
#x-terminal-emulator -geometry 80x24+10+10 -ls -title "$VNCDESKTOP Desktop" &
#x-window-manager

unset SESSION_MANAGER is used to remove error something like ‘Could not acquire name on session bus
/usr/share/gnome-session/sessions would have number of .session files and you can use any of them into xstartup file
