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

Tue Oct 25 18:16:12 UTC 2022

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?

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

Thanks.
