Problem: VNC Display Quirks

Manifestation:

• Unable to fully interact as expected with GUIs/terminals in VNC workspace.
• Borders around GUIs in a given VNC display (e.g. VNC:5) disappear. Window manager pull-down menu(s) inactive/unresponsive.

Solution/Recovery:

• Level 1: If confined to a single, isolated VNC workspace:
  • Attempt re-start of individual VNC server (as user@shimmy.ucolick.org) with appropriate arguments:

     
       user@shimmy.ucolick.org > /home/user/remote/bin/restart_vnc_server X 
       

    ...where X is an integer number correspnding to the appropriate VNC server (e.g. 5).

If level 1 recovery unsuccessful, attempt levels 2, 3 & 4.
• Level 2: Attempt to re-start fvwm:

  Click VNC background to access root menu. Select Restart Fvwm.

• Level 3: (if level 1 unsuccessful). Attempt restart of window manager:

  In xterm:

  fvwm -c "Restart"

• Level 4: (if level 1 and 2 unsuccessful). Attempt re-start of individual VNC display (e.g. 5):

  In xterm:

  vncserver -kill :5

  cd .vnc

  vncserver :5 -depth 24 -listen tcp -alwaysshared -geometry 1910x1040 -IdleTimeout 2000000 -name ":5 AO Spare 2"

  Refer to the following to verify command syntax:

  /usr/local/lick/bin/start_vnc_servers
