No Notifications in Qubes OS 4.2

[Minio]

I think it is fair to say yes.

You had the issue, I had it and at least two users here:

Has anyone installed i3wm 4.22

Hmm okay. I do not see any notifications. Could a missing dependency be the issue?

Has anyone installed i3wm 4.22

I switched to 4.2 today, no issue so far with my apps and same for Firefox. I had the notification issue you previously talked about in this thread, I fixed it by creating a dbus service that runs xfce4-notifyd at startup. I also had to fix an i3 4.22 issue with primary/nonprimary monitor that was not working with the help of this commit.
