Already did; it did work, thanks (and yes, it's always Virtual-1 for some reason).

I couldn't understand it very well from the bug report, why isn't it automatically working on some DEs/WMs?

The QXL driver notifies the DE/WM about the new resolution.

Many DEs/WMs do not listen for such a notification.

Now, could we focus on the nasty bug with file transferring? As already mentioned, the -f and -o options are serving of absolutely nothing...

Does it help if you run spice-vdagent -xd -f $HOME ?

Did you try other directories with -f ?

Uri.

Thanks.

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

Try the workaround mentioned on the bug, run on the guest (after resizing remote-viewer's window):

    xrandr | grep Virtual                  # look for the connected one

    xrandr --output Virtual-0 --auto # may be Virtual-1 instead of Virtual-0

Uri.

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.

Hi Carlos,
   my main curiosity was about the need of the agent for resize.
I did some tests and with both Windows and Linux it appears that the
agent is needed.
At this point I would try looking at the agent logs.
Is your system using Xorg or Wayland ?

I agree with Frediano that (with a recent QXL device) the arbitrary resolution update is done via QXL.

Note that it does not work for all Desktop Environments, and I apparently it doesn't work for AntiX Linux (default DE).

If you can, try to run with GNOME/X11 and see if that works.

Regards,

With all SPICE stuff properly installed, everything works out of the box: clipboard, resizing, file transfer from host to guest. With "properly installed" I mean: installed SPICE drivers manually from virtio-win ISO by loading them since the Windows installation beforehand, then once booted into Windows downloaded the vdagent ZIP from spice-space website and manually installed the service according to instructions.
