[Spice-devel] Vdagent not working on a Debian guest

[Carlos González]

So I did more tests.

First, AntiX Linux by default doesn't use "desktop environments" but
"window managers", being the default IceWM. Also, it doesn't use SystemD at
all; SysV instead. Regarding Xorg or Wayland, it's Xorg.

Well, of course it's needed! That's per basic instructions...

Since there's no SystemD here, neither journalctl command. So tried running
both spice-vdagentd and spice-vdagent with debugging:
sudo /usr/sbin/spice-vdagentd -x -d -d
spice-vdagent -f /path/to/folder -x -d -d

When resizing the remote-viewer window, no logs whatsoever, and of course
neither resolution update. Also, using the -f option served of nothing;
exact same error mentioned before...
Neither anything at all related in /var/log/Xorg.0.log
*Only* clipboard sharing seems to work

By chance, do you think you could give the live ISO a try? It's a live
system, and the "Base" version is a CD size, not even a DVD...

Thanks again for your attention.
