gnome 40, missing org.freedesktop.UPower.KbdBacklight about gnome-keyboard-backlight-menu

[lovasoa]

This should require only a recent version of upower.

What distribution are you using?

[lovasoa]

This property seems to have been supported for a long time: https://github.com/freedesktop/upower/blob/0e256ece04a98d3d202ed9640d33c56aaaeda137/dbus/org.freedesktop.UPower.KbdBacklight.xml

[mfauvain]

Arch, and upower-0.99.13-1 which I believe is the latest

[lovasoa]

What is the exact error message you are seeing ?

[lovasoa]

Maybe you are affected by this bug: https://gitlab.freedesktop.org/upower/upower/-/issues/73 ?

[mfauvain]

Possibly, however I tried the solution proposed there with no luck.

[lovasoa]

does setting your keyboard backlight via

dbus-send --type=method_call --print-reply=literal --system --dest='org.freedesktop.UPower' '/org/freedesktop/UPower/KbdBacklight' 'org.freedesktop.UPower.KbdBacklight.SetBrightness' int32:1

and

dbus-send --type=method_call --print-reply=literal --system --dest='org.freedesktop.UPower' '/org/freedesktop/UPower/KbdBacklight' 'org.freedesktop.UPower.KbdBacklight.SetBrightness' int32:0

work ?

[lovasoa]

What are the logs from upower ?

journalctl | grep -i upowerd

[mfauvain]

First command did not work:
Error org.freedesktop.DBus.Error.UnknownMethod: Object does not exist at path “/org/freedesktop/UPower/KbdBacklight”

And second one does not give anything related to keyboard backlight.

[lovasoa]

Then the problem probably isn't with this extension. You should probably open an issue with upower

[mfauvain]

ok. thx.
just FMI, what version of uPower do you have? it seems the version that was working on Arch is 99.7, some years ago..

[lovasoa]

I have the latest fedora version:

❯ upower --version
UPower client version 0.99.13
UPower daemon version 0.99.13

[mfauvain]

I have the same version

UPower client version 0.99.13
UPower daemon version 0.99.13

So I guess the issue is not with UPower.. will revert if I find something.
