it seems to me that the vnc server is running but there is no window manager inside it.

do you run the vnc server as root?
the file /etc/sysconfig/vncservers defines the servers to run when you use vnc as service. could you show it?

[Stuart Browne]

Yeap..

That'd be the VNC server's X server not having a windows manager running, thus only showing the VNC tools.

What does your '/etc/sysconfig/vncserver' file look like?

It should normally have a line simialr to:

VNCSERVERS="0:root"

Where '0' is the display number, and 'root' is the user the server is to run as.

If you are also running an X server on the console, the '0' would be at least '1' (as the console is always display '0').

[Fadia Almarei]

the data on the file vncservers is

[root@ORA1 sysconfig]# more vncservers
# The VNCSERVERS variable is a list of display:user pairs.
#
# Uncomment the line below to start a VNC server on display :1
# as my 'myusername' (adjust this to your own). You will also
# need to set a VNC password; run 'man vncpasswd' to see how
# to do that.
#
# DO NOT RUN THIS SERVICE if your local area network is
# untrusted! For a secure way of using VNC, see
# <>.

#VNCSERVERS="1:myusername"
#VNCSERVERARGS[1]="-geometry 800x600"


and i start vncserver as a root

[Claudio Cilloni]

could you show the file /root/.vnc/xstartup ? this is a script executed by the vncserver command to run the window manager

[Gopi Sekar]

uncomment VNCSERVERS and set it as,

VNCSERVERS=1:root

and see whether it solves your problem

the xstartup file
#!/bin/sh

# Uncomment the following two lines for normal desktop:
# unset SESSION_MANAGER
# exec /etc/X11/xinit/xinitrc

[ -x /etc/vnc/xstartup ] && exec /etc/vnc/xstartup
[ -r $HOME/.Xresources ] && xrdb $HOME/.Xresources
xsetroot -solid grey
vncconfig -iconic &
xterm -geometry 80x24+10+10 -ls -title "$VNCDESKTOP Desktop" &
twm &

i try to put VNCSERVERS=1:root put also it does not work

[Gopi Sekar · Accepted solution]

# Uncomment the following two lines for normal desktop:
# unset SESSION_MANAGER
# exec /etc/X11/xinit/xinitrc

uncomment the above lines and comment rest of the lines in xstartup file. see whether it solves your problem

My suspect goes to twm.
Verify it is installed:

# which twm
/usr/X11R6/bin/twm

You can do another thing. You say you run vncserver from root, so I think you run command:

# vncserver :1

if you did so, try this in another shell

# export DISPLAY=:1
# twm

this should bring the twm window manager into the vnc display.
