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):
#!/bin/sh # Start up the standard system desktop unset SESSION_MANAGER unset DBUS_SESSION_BUS_ADDRESS #exec /etc/X11/xinit/xinitrc /usr/bin/mate-session [ -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
