Keyboard backlight notification in GNOME is gone

maxgiggs · 2018-08-29 11:51:54

Hi everyone!

Recently, I discovered the `lostfiles` script and then I accidentally removed some system files... well, I broke my system. In particular gdm, and pulseaudio stopped working. By removing and installing some packages I was apparently able to restore the system to its previous state.

However, I noticed that the keyboard backlight overlay notification in GNOME, which previously worked out of the box (ThinkPad T470), is gone. Is this issue related with my accident? Or is it a general issue related to some recent system update?

Thanks in advance!

Update: I noticed that also the slider in gnome-settings which control the keyboard light is gone!

Here's other relevant informations. `dbus-monitor` doesn't show any activity when the keyboard backlight key (fn+spacebar) is pressed. Moreover, `upower --dump` does not list any keyboard device

Check

pacman -Qkk | grep -v " 0 altered files"

and fix suspicious packages.

To my eyes, nothing seems particularly suspicious. Moreover, I have already reinstalled all the system packages; therefore, I don't know what else to do.

This is however very strange; the keyboard backlight works, but the system (i.e., I believe, `upower`) has become completely blind to it.

maxgiggs · 2018-08-29 14:07:44

Ha ha! I found the culprit!

Indeed, `upower` was updated yesterday and the new version seems to create several problems (i.e. keyboard backlight and ac-adapter notifications). Rolling back to the previous one solves the all the issues.

Should I open a bug report on the Bugtracker?

maxgiggs · 2018-08-29 16:52:25

It seems that `upower` has been moved to gitlab. For the interested, the issue can be found here https://gitlab.freedesktop.org/upower/upower/issues/68
