Flagging using tvflag

The interactive flagging program tvflag must be run on an 8-bit (a.k.a. PseudoColor) display. Most modern desktops are so color rich, they cannot be effectively run in an 8-bit display, though twm and fvwm can. For example, on Linux you can start a second X session from another console (e.g. ctrl-alt-F2):

  % startx -- -depth 8 :1

or use VNC:

  % vncserver :1 -depth 8 -cc 3 -geometry 1024x768
  % vncpasswd
  % vncviewer :1

  % xmtv &
  % tvinit server=xmtv@localhost
  % tvflag vis=vis0 server=xmtv@localhost

  % vncserver -kill :1
