Keep a remote X11 app running after disconnecting the Session

Xpra is the tool of choice 🙂
Install xpra on server and client like:

[code language=”bash”]

root@h2545526:~# apt install xpra
.
.
xpra (2.1.3+dfsg-1ubuntu1) wird eingerichtet …

[/code]

start e.g. firefox on the server:
[code language=”bash”]
xpra start :100 –start-child=firefox
[/code]

now connect from remote through Ssh:
[code language=”bash”]
xpra attach ssh/user@serverFQDN/100
[/code]

With xpra firefox remains active on the server even when the client disconnects 🙂

Big advantage for e.g. large downloads.
