On a current Ubuntu with Wayland/GNOME, when my battery is low the battery indicator on the top right goes red. On my previous laptop I had Ubuntu/X/GNOME, and a popup notification used to appear indicating that the battery is critical and the computer is about to shut down. Now it just goes dark. Is there a way to re-enable such notifications?
I see no option in the power settings, GNOME tweak tool or dconf.

I saw the reverse question How to get rid of low battery warning message? from 2012. Btw, gconf-editor does not seem to be installable anymore from Ubuntu (gconf-editor has no suggestions, sudo apt install gconf-editor does not find it), although it is alive and well in the online documentation at https://help.ubuntu.com/community/GConfEditor and https://help.gnome.org/users/gconf-editor/.
This is the same question as No low battery popup notification in 16.04 and Ubuntu 18.04 not showing low battery warning
This is different to
- No warning for low battery No low battery notification appears before premature low battery shutdown on Ubuntu 18.04 where the battery estimation is wrong
- Ubuntu 18.04 not showing low battery warning which gives help to set the hibernate action when battery is critical
It may be similar to:
- Ubuntu 18.04/i3wm - No low battery notifications (which uses i3wm)
- No Low Battery Notifications or Low Battery Action on 16.10/17.04/17.10/18.04.4 (unresolved)
dconf write /apps/gnome-power-manager/notify/low_capacity truehelps ... I haven't tested it and don't even know if it's still valid ... I simply took it from your first linked post as you seem to have great hope in setting that key, so that's how to set it in current versions. – Raffa Dec 15 '23 at 12:58
