Qubes 4.0: Device Widget disappeared

[gaxi...@gmail.com]

The system tray device widget is not visible anymore. It was there after a fresh 4.0 install but disappeared after some days. How can i get it back?

Were you playing with the tooltray settings? I tried but couldn't figure
out how to hide it. Apply any updates right before it disappeared?

I did updates after the install, maybe that removed it.
Anyway: can anyone tell me the CLI command to start that widget?

python3 -mqui.tray.devices

python3 -mqui.tray.domains

'python3 -mqui.tray.domains' works fine but 'python3 -mqui.tray.devices' gives me an error:

Any idea what is missing on my system?
Thanks!

Good news: After today's dom0 update, the widget re-appeared!

Bad news!: After today's Dom0 update, I got exactly this problem. Trace is the same as reported above. I never encountered it before. Is there something I can do?

Looks like that's a recent bug that has already been fixed:
https://github.com/QubesOS/qubes-issues/issues/4386, so the device
widget should reappear after the next round of updates.

I updated from the qubes-dom0-current-testing repo but the problem is still there :(

fabr...@statebox.io:

Probably best to mention that on issue 4386, if it's not resolved.

I observed the following:

Starting a vm with
$ qvm-start --hddisk dom0:dataimage.img vm-name
makes the devices widget disappear.

But luckily
$ python3 -mqui.tray.devices &
re-creates it again.

Starting a vm without an external HDD image leaves the widget untouched.

this should also work:
$ qui-devices &

Ok, I have some news. My tray icons reappear if I log in using xfce4. The problem seems to be i3-related. Has something been modified in the last dom0 uupdates so that i3-bar is not able anymore to fetch the icons?
