Persistent VNC Session for users for CentOS

If you are intending to setup a persistent VNC Session for selected users, you can edit the global settings at /etc/sysconfig/vncservers.

# vim /etc/sysconfig/vncservers 

# The VNCSERVERS variable is a list of display:user pairs.
# Uncomment the lines below to start a VNC server on display :2
# 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 this URL:

# Use "-nolisten tcp" to prevent X connections to your VNC server via TCP.

# Use "-localhost" to prevent remote VNC clients connecting except when
# doing so through a secure tunnel.  See the "-via" option in the
# `man vncviewer' manual page.

# VNCSERVERS="2:myusername"
# VNCSERVERARGS[2]="-geometry 800x600 -nolisten tcp -localhost"

VNCSERVERARGS[2]="-geometry 1280x800 -depth 16"
VNCSERVERARGS[3]="-geometry 1024x768"

Once done, you just restart the vncserver services
# service vncserver restart
