I realise I neglected to mention that you should run "screen -r" to reattach to the running screen next time you want to interact with the xboard server. See the man page, though, for good use of the -d and -r switches. > > The real mystery now is how to run xboard! :) > > This line: > > > fox$ xboard # Fox connects to the xboard server in the same way > > that flik does. > > Just to clarify, I think you meant: > > fox$ xboard -ics Flik # Fox connects to Flik server the same way other > players (netizens) do.

Ah, OK. So Flik rather than Lizard is the server. I think I misunderstood there. In that case you want to make Lizard the client. Hmm. I don't know of a program like screen that works for X connections (i.e. allows you to detach and reattach them). There are, however, programs that will run the client on a virtual display and you can then view that display on Fox. For that, look at a VNC or RDP server. Here, the basic workflow would be similar to screen; you start a VNC or RDP server on lizard, you connect a viewer program on fox to the display on lizard, you start xboard on the virtual display, you can then disconnect and reconnect to that virtual display.
