Battery low notifications go away with `dunst`

yesterday, thanks to @m-col, I manage to have beautiful popup notifications for my battery from within qtile’s bar and even sound and brightness bars as I change them with the keyboard: However it is still not behaving quite as I expected.

I expected the notifications for a low battery to be of urgent/critical priority and it is red indeed. I configured my dunst so that low and normal notifications go away quite quicly, but critical/red ones never go away!

This is what I observe when I run either

notify-send "ERROR" "this is an error" -u critical
notify-send "NORMAL" "this is a normal message" -u normal
notify-send "LOW" "this is nothing important" -u low

or

dunstify "ERROR" "this is an error" -u critical
dunstify "NORMAL" "this is a normal message" -u normal
dunstify "LOW" "this is nothing important" -u low

But this is not the case with the critical battery low notifications from qtile.

I do not really understand the code of the libqtile.widget.Battery class, could anyone help fix that?

The widget does send messages marked as “urgent”. However, I suspect your issue is that the notification is also sent with a set timeout (10 seconds) which dunst is, presumably, honouring.

The widget should send an urgent notification so something’s going wrong by the sounds of it. Let me take a look.
