[SOLVED] notify-send --- --urgency equals critical doesn't work?

[chimak111]

Looks like kdialog --passivepopup "whatever message" is the way.

According to man notify-send,

OPTIONS
-u, --urgency=LEVEL Specifies the urgency level (low, normal, critical).

-t, --expire-time=TIME
       The  duration,  in milliseconds, for the notification to appear on screen.  
       (Ubuntu's Notify OSD and GNOME Shell both ignore this parameter.)

notify-send --urgency=critical "DONE"' doesn't work for me: the notification disappears after a few seconds.

I can extend the time for which the notification is on the screen with notify-send --expire-time=50000 "DONE" but I want a notification to go away only when I dismiss it. Is that possible?

My tea-timer (sudo apt install kteatime) tells me it's possible to have a notification stay visible until dismissed. Does "KDE" have its own notification system? If so, where is that info to allow users to have their own custom notifications?

I think it may be, because it changed some time after 18.04. In 20.04, the notification settings looks like this:

and the one set by notify-send -u critical smile persists as I'm typing this. With 18.04 notifications of any urgency didn't last long, even in the notifications applet, and I often missed them.

Thanks! The nice thing with the 20.04 notification is a timer showing its "age" (in minutes).
