Some Gnome timeout imply proof of life requirement on server side to maintain or restore Xfce Session.

Hello everyone,

When using Xfce remotely,

a kind of Gnome timeout occurs after a few minutes.

A server-side proof-of-life, such as a keystroke, then becomes necessary 
to maintain or restore the Xfce session, which is a shame on a server 
that's supposed to be available 24 hours a day without a physical human 
presence.
Note that the problem does not occur on Ubuntu or Debien when Xfce 
replaces Gnome.

Thank you in advance for your insightful feedback !
