Dear Maintainer,

After Bookworm -> Trixie upgrade, I couldn't change brightness anymore with the
hotkeys.

When running "xfce4-power-manager --debug" and pressing a hotkey, I saw:
TRACE[xfpm-brightness-polkit.c:160] xfpm_brightness_polkit_set_level():
Executing command: pkexec /usr/sbin/xfpm-power-backlight-helper --set-
brightness 1
TRACE[xfpm-brightness-polkit.c:164] xfpm_brightness_polkit_set_level(): Failed
to set value: Failed to execute child process “pkexec” (No such file or
directory)
Then I found that command in /usr/lib/x86_64-linux-
gnu/xfce4/panel/plugins/libxfce4powermanager.so , which belongs to xfce4-power-
manager-plugins.

I use network-manager, which in Bookworm depended on policykit-1, which depends
on pkexec.
But in Trixie it no longer depends on policykit-1, so (that and) pkexec got
autoremoved.
That's why in my case, it worked fine in Bookworm and broke in Trixie.

Thanks, Gert

Adjusting the severity to "important" since this bug breaks
functionally of the package.

I can confirm the issue. It would be nice if we could have this fix in
trixie, seems like a simple "Recommends: pkexec" or "Depends: ..." would
fix this.
I only tested it by installing "pkexec" manually.
