I have a backup script that runs once a day with root privileges. It's
handled by systemd timer and service units. I would like to have a
desktop notification text when the backup is ready.
What I have tried so far: I don't use normal desktop, only i3 window
manager. I installed notify-osd package and started its daemon as a
normal user. Running a command "notify-send foo" shows "foo" text like I
expected. But when "notify-send" runs as root no notification text
appear anywhere.
How can I get notifications working in plain window manager setup? And
hopefully not only this backup script example but for other programs
too, like Network Manager's notifications. I'm not really interested in
work-arounds like "DISPLAY=:0 xmessage -timeout 5 foo".
I don't know whether this qualifies as a work around that you are not
interested in, but I have found that this works. From you script use
the following:
sudo -u <username> notify-send foo
Since the script is running with root privileges, sudo will not need a
password to run the notify-send command as a lesser privileged user. I
haven't tried this from a script, but did do it from the keyboard. I
verified that notify-send would not send a notification to me when
sudo'ed as root, and then used the above command. It did indeed work.
The <username> that you use is the username that you are normally logged
in as.
