VNC issue

VNC Black screen issue

We work around it by changing your default desktop from GNOME to MATE.

1. Terminate any existing vncserver processes (use "vncserver -list" to list any current sessions, and "vncserver -kill :3" to terminate the session, in this example it is terminating the vncserver using port 3, aka 5903)

2. Modify your "$HOME/.vnc/xstartup" script to look like the following (we've also updated the wiki https://docs.uabgrid.uab.edu/wiki/Setting_Up_VNC_Session#Configure_the_Cluster_Desktop):


 * 1) !/bin/sh

unset SESSION_MANAGER unset DBUS_SESSION_BUS_ADDRESS
 * 1) Start up the standard system desktop

/usr/bin/mate-session
 * 1) exec /etc/X11/xinit/xinitrc

[ -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 &

3. Start a new "vncserver" session

4. Create your SSH tunnel

5. Connect using the VNC client of choice
