TTBOMK (being former Debian package maintainer of xboard) xboard will need a DISPLAY to run interactively. ssh -X was already mentioned, but if the connection gets lost so does any X application running in ssh -X. screen won't help due to the X requirement. VNC and/or RDP (e.g. via xrdp) would allow persistent X applications, but both have some overhead you'd prefer to avoid (and I personally dislike both of them for the fixed display size of a running session). So far so bad. xpra might help, though. Consider the following sample session. fernst is my powerful (ahem...) workstation, c01n01v01 is a remote virtual server I just had running (still running Squeeze w/ backports, but still enough to illustrate my point). Starting xboard on c01n01v01: :) fe@fernst:~$ ssh fe@c01n01v01 Linux c01n01v01zfs 2.6.32-26-pve #1 SMP Mon Oct 14 08:22:20 CEST 2013 x86_64 The programs included with the Debian GNU/Linux system are free software; the exact distribution terms for each program are described in the individual files in /usr/share/doc/*/copyright.
