Blank Screen of VNC

Standard

Recently I found already running VNC landed with blank screen out of the moon. Debugging revealed after uninstalling some packages related with Window/Desktop managers, existing xstartup of VNC failed to call Desktop manager. Experienced frequently with Gnome. My VNC again came back to life with below xstartup which instructs VNC to call DM explicitly.

.vnc/xstartup

#!/bin/sh

# Uncomment the following two lines for normal desktop
#Helpful to get just simple gnome
unset SESSION_MANAGER
exec /etc/X11/xinit/xinitrc

[ -x /etc/vnc/xstartup ] && exec /etc/vnc/xstartup
[ -r $HOME/.Xresources ] && xrdb $HOME/.Xresources
xsetroot -solid grey
vncconfig -iconic &
#set the geometry as per requirement
xterm -geometry 80x24+10+10 -ls -title "$VNCDESKTOP Desktop" &
#call DM
#twm&
#icewm&
gnome-session&
