Screenshot of brightness indicator in XFCE

Description of problem:
When I'm adjusting the display brightness (the screen backlight) using the keyboard, XFCE displays a progress bar, indicating the current intensity. In Fedora 23, the progress bar seems to have a zero width, and the "sun" icon is also missing (see the attached screenshot).

Version-Release number of selected component (if applicable):
1.5.2-1.fc23

How reproducible:
Always (I tried on two different netbook models)

Steps to Reproduce:
1. Use the keyboard to adjust the backlight
2.
3.

Actual results:
Empty OSD (on-screen display)

Expected results:
Progress bar indicating where the current brightness is, between min and max.

Additional info:
Please note that adjusting the brightness works, only the XFCE indicator is empty (so it's just a minor annoyance).  This works properly in Fedora 22, apparently using the same kernel 4.2.5.  Here are the kernel brightness values:
$ grep . /sys/class/backlight/acpi_video0/*
/sys/class/backlight/acpi_video0/actual_brightness:6
/sys/class/backlight/acpi_video0/bl_power:0
/sys/class/backlight/acpi_video0/brightness:6
grep: /sys/class/backlight/acpi_video0/device: Is a directory
/sys/class/backlight/acpi_video0/max_brightness:8
grep: /sys/class/backlight/acpi_video0/power: Is a directory

Comment 1 Mukundan Ragavan 2015-11-06 12:39:31 UTC 
I have noticed this myself and have been meaning to file an upstream bug report about it ...

I will file this upstream (finally) later today.

xfce4-power-manager log

I attached a debug log from xfce4-power-manager, covering startup and changing the brightness via the keyboard. I guess the empty OSD is caused by two different issues:

- not finding the xfpm-brightness-lcd icon in the Fedora or Adwaita themes (this icon can be found under /usr/share/icons/hicolor/*/status/xfpm-brightness-lcd.png under Fedora 22, can't check Fedora 23 right now)

- missing method GetMaxBrightness from org.freedesktop.UPower.KbdBacklight (this should exist, according to upower upstream documentation)

http://upower.freedesktop.org/docs/KbdBacklight.html#KbdBacklight.GetMaxBrightness
Comment 3 Woi 2015-12-25 11:05:36 UTC 
Just updated from Fedora 22 to Fedora 23 and bumped into this issue.

$ cat /etc/os-release |grep PRETTY
PRETTY_NAME="Fedora 23 (Twenty Three)"
$ find /usr/share/icons/hicolor/ -iname xfpm-brightness*

Can you folks try this build?

Thanks for the build.

$ sudo dnf install -q -y https://kojipkgs.fedoraproject.org//work/tasks/8978/12228978/xfce4-power-manager-1.5.2-2.fc23.x86_64.rpm
$ xfce4-power-manager
$ killall xfce4-power-manager
$ xfce4-power-manager

Works for me.

PS: Just saw the --restart option of xfce4-power-manager
Comment 6 Laurentiu Pancescu 2015-12-30 09:29:21 UTC 
I tried the i686 version yesterday evening, and it seems to work fine. The slider is displayed correctly while adjusting the brightness, and things like screen blanking and switching from AC to battery are handled just as before.  I didn't notice anything unusual in the few hours I tested it.

Thank you, Mukundan, for taking the time to build a fixed package!  With no reaction from upstream, I didn't have much hope of this being addressed soon, and certainly not before 2016 (I was thinking about waiting until at least mid-January before asking if you would consider incorporating my proposed patch directly into Fedora).

I was hoping for a new upstream release. But it is probably worth to push an update. I will push an update in a day or two ...

Since there was no reaction upstream so far, I created a new bug:
https://bugzilla.xfce.org/show_bug.cgi?id=12438
Maybe no one looks on already closed bugs (And I'm not allowed to reopen it)
