Keep a remote X11 app running after disconnecting the Session
Xpra is the tool of choice 🙂
Install xpra on server and client like:
root@h2545526:~# apt install xpra . . xpra (2.1.3+dfsg-1ubuntu1) wird eingerichtet ...
start e.g. firefox on the server:
xpra start :100 --start-child=firefox
now connect from remote through Ssh:
xpra attach ssh/user@serverFQDN/100
With xpra firefox remains active on the server even when the client disconnects 🙂
Big advantage for e.g. large downloads.
