Authentication needed to run xfpm-power-backlight-helper as super user

On startup, any time I hit the brightness function keys, or when the screen tries to autodim after a certain period of time, I get this popup dialog box requiring my password. If I hit brightness up 5 times, I have to enter my password 5 times. Annoying. Power manager runs from startup:
settings > session & startup > application autostart > power manager

Does anyone know how to get xfce4-power-manager to call xfpm-power-backlight-helper as root?

Re: Authentication needed to run xfpm-power-backlight-helper as super user

Which distro?
Which version of Xfce and xfce4-power-manager?
Any error messages in your log files?

One way to debug this is to quit xfce4-power-manager:

xfce4-power-manager -q

...then run it in debug mode:

xfce4-power-manager --no-daemon --debug

...and note the messages that display in the terminal window when the password prompt displays.

Also useful would be the results of:

xfce4-power-manager --dump

Re: Authentication needed to run xfpm-power-backlight-helper as super user

Sorry Toz, shit post by me, no additional detail given!
Xubuntu 16.10 just installed,
xfce4-power-manager 1.6
xfce version: not sure, xfce4 --version & xfce --version return nothing. Just upgraded to 16.10 though so whichever is the latest stable?
Looking through these logs, I wonder if this is related to my issue whereby the laptop was refusing to suspend? Don't know if it's still an issue since the upgrade though...

Re: Authentication needed to run xfpm-power-backlight-helper as super user

Well, the log files look right. Must be an issue with polkit then,

First, you said you upgraded to 16.10. Did you upgrade from 16.04?

Secondly, some more investigations. Lets start with these:

ps -ef | grep polkit
cat /usr/share/polkit-1/actions/org.xfce.power.policy
apt-cache policy libpolkit-backend-1-0
groups
pkaction | grep xfce
pkaction --action-id org.xfce.power.backlight-helper --verbose

Re: Authentication needed to run xfpm-power-backlight-helper as super user

I've added code tags to your above posts to make them more readable (the code parts).

Your system appears to be missing a required policykit action file: /usr/share/polkit-1/actions/org.xfce.power.policy

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE policyconfig PUBLIC
 "-//freedesktop//DTD PolicyKit Policy Configuration 1.0//EN"

This is the file that defines access to the backlight helper executable allowing you to change the backlight without needing to specify the root password. Try creating the file with root privileges. You may need to log out and back in again for it to take effect. You can test if polkit is processing it via the two pkaction commands above, which should return:

$ pkaction | grep xfce
...
org.xfce.power.backlight-helper
...
$ pkaction --action-id org.xfce.power.backlight-helper --verbose

Re: Authentication needed to run xfpm-power-backlight-helper as super user

Huh, strange. Tried all that, added </policyconfig> at the end of the first code block as that was chopped off, restarted, no change.
Changed

<defaults>
      <allow_any>no</allow_any>
      <allow_inactive>no</allow_inactive>
      <allow_active>yes</allow_active>

to

<defaults>
      <allow_any>yes</allow_any>
      <allow_inactive>yes</allow_inactive>
      <allow_active>yes</allow_active>

restarted, no change. Though that change affects the outcome of the verbose code line, changing the implicit any & inactives to yes, as you'd expect...

Re: Authentication needed to run xfpm-power-backlight-helper as super user

It should definitely be "no no yes" as that's what the file in the package has.

What do the following commands return:

pkaction | grep xfce
pkaction --action-id org.xfce.power.backlight-helper --verbose

The other thing you could try is to reinstall the power-manager package:

apt-get install --reinstall xfce4-power-manager

...as well as the policykit packages:

apt-get install --reinstall policykit-1

Edit:
Can you also post back:

apt-cache policy xfce4-power-manager

Re: Authentication needed to run xfpm-power-backlight-helper as super user

That output looks fine.

I'm not sure how much farther I'm going to be able to go with this as I am by no means a policykit guru, but I can offer a couple more suggestions:

1. Since your install of xfce4-power-manager was missing a file, purging and re-installing it might help:

sudo apt-get purge xfce4-power-manager
sudo apt-get install xfce4-power-manager

...log out and back in again to test.

2. Perhaps if you tried to get some more policykit debug information, it might identify where the issue is. To do so, edit the file /lib/systemd/system/polkitd.service, comment out the "ExecStart=" line and add the following directly below it:

ExecStart=/bin/sh -c 'G_MESSAGES_DEBUG=all /usr/lib/policykit-1/polkitd > /tmp/polkitd.log 2>&1'

...then kill the process:

sudo killall polkitd

...then try to adjust the brightness and have a look at the /tmp/polkitd.log file to see what debug information was displayed.

Please remember to mark your thread [SOLVED] to make it easier for others to find

Re: Authentication needed to run xfpm-power-backlight-helper as super user

Interesting, right so purge removed the problem, install reintroduced it, so at least that confirms this is the culprit.

Re: Authentication needed to run xfpm-power-backlight-helper as super user

Does the /usr/share/polkit-1/actions/org.xfce.power.policy file still exist? Are its contents the same as the ones in post #6?

Also, did you re-install policykit-1 as per post #8?

Re: Authentication needed to run xfpm-power-backlight-helper as super user

It was the same yeah. I didn't reinstall polkit but have now. Both times I've done this i've had to use sudo - I assume this isn't indicative of a problem, but just in case. Restarting now.

Edit: no change. Man.... I'm surprised that this is so tough. Tempted to just purge it to get rid of the annoying boxes each time, though I imagine that means I have no power indicator or anything else...

Re: Authentication needed to run xfpm-power-backlight-helper as super user

Can you post back the contents of these files:

- /etc/polkit-1/localauthority.conf.d/50-localauthority.conf 
- /etc/polkit-1/localauthority.conf.d/51-ubuntu-admin.conf

Re: Authentication needed to run xfpm-power-backlight-helper as super user

Something interesting:

In post #3, "xfce4-power-manager --dump" showed version 1.6.0, but in post #10, "apt-cache policy xfce4-power-manager" is showing 1.4.4 installed.

Can you confirm which version is installed? Run both commands again.
Did you manually or somehow else install version 1.6.0 of the power-manager at any time on this system?
What does this return?

locate xfce4-power-manager | grep bin

Re: Authentication needed to run xfpm-power-backlight-helper as super user

You're a bloody genius. So yeah, related to my comment earlier about the power manager being a pain and not suspending, I tried to manually install a newer version of power manager to see if it fixed it. It didn't. But that might explain bits of different versions lying around my system. Brilliant deduction dude.

locate xfce4-power-manager | grep bin
/home/simon/.cache/upstart/update-notifier-crash-_var_crash__usr_bin_xfce4-power-manager.1000.crash.log.1.gz

/usr/bin/xfce4-power-manager
/usr/bin/xfce4-power-manager-settings
/usr/local/bin/xfce4-power-manager
/usr/local/bin/xfce4-power-manager-settings

Here's v1.6:

xfce4-power-manager --dump
---------------------------------------------------
       Xfce power manager version 1.6.0
With policykit support
With network manager support
---------------------------------------------------
Can suspend: True
Can hibernate: False
Authorized to suspend: True
Authorized to hibernate: False
Authorized to shutdown: True
Has battery: True
Has brightness panel: True
Has power button: True
Has hibernate button: True
Has sleep button: True
Has LID: True

Here's v1.4.4-4:

apt-cache policy xfce4-power-manager
xfce4-power-manager:
  Installed: 1.4.4-4ubuntu2
  Candidate: 1.4.4-4ubuntu2
  Version table:
 *** 1.4.4-4ubuntu2 500
        500 http://mirror.math.ucdavis.edu/ubuntu yakkety/universe amd64 Packages
        100 /var/lib/dpkg/status

So what do we think, can I somehow purge 1.4.4-4 and have everything 1.6? Or vice-versa?

Thank you so much for your continued persistence!

Re: Authentication needed to run xfpm-power-backlight-helper as super user

How did you install 1.6.0? Can you use the same method to uninstall?

Re: Authentication needed to run xfpm-power-backlight-helper as super user

Awesome. I installed (configure/autogen, make, make install) 1.6 to try to fix the hibernate bug, which it didn't. But I guess installing it this way didn't properly install it everywhere. Which may have been why it didn't fix the hibernate bug, but wonderfully not only did it not solve one problem, it later created another. Weird. Just did

sudo make uninstall

in the 1.6 folder in home, and restarted, and voila, sorted.
A thousand thank-yous. Please PM me your paypal address so I can send you some Molsons (or Kokanees)
edit: p.s. how can I mark this solved?

Glad to hear.

To mark this thread as solved, edit your first post and prepend [SOLVED] to the subject line.
As for the beers, buy yourself some Canadians and enjoy. I'll do the same.
