Bug#773743: xfce4-power-manager: Suspend fails (requests authentication in order to suspend)

[Justin <s0m3f00l@gmail.com>]

Package: xfce4-power-manager
Version: 1.6.6-1
Followup-For: Bug #773743

Hello,

  I run a thinkpad 495 laptop with tlp and this bug still exists. I believe the
bug has to do with the way the package adds rules to the systemd polkit. It
appears some rules and there subsequent config are missing. I also noticed that
with workarounds using the xfce4-power-manager settings the laptop would often
suspend before locking and when coming back it would briefly show the contents
of the unlocked system.

I have added what I did to fix the authentication errors below:

In order to get suspend issue corrected perform the following:

    1) Create the '/etc/polkit-1/rules.d' directory

 $ sudo su
 # mkdir /etc/polkit-1/rules.d

    2) Correct the permissions for the directory

 # chmod 755 /etc/polkit-1/rules.d

    3) Create a new file called /etc/polkit-1/rules.d/85-suspend.rules

 # vi /etc/polkit-1/rules.d/85-suspend.rules

    4) Add the following text to the new file called
'/etc/polkit-1/rules.d/85-suspend.rules'

polkit.addRule(function(action, subject) {
    if (action.id == "org.freedesktop.login1.suspend" &&
        subject.isInGroup("users")) {
        return polkit.Result.YES;
    }
});

    5) Correct the permissions on the file
'/etc/polkit-1/rules.d/85-suspend.rules'

 # chmod 644 /etc/polkit-1/rules.d/85-suspend.rules

    6) Edit the file
'/usr/share/polkit-1/actions/org.freedesktop.login1.policy' and change the
"suspend" rules to <allow_any>yes</allow_any>

The process is similar to fix the backlight modification authentication errors.

    1) Create the '/etc/polkit-1/rules.d' directory ("if it doesn't exist")

 $ sudo su
 # mkdir /etc/polkit-1/rules.d

    2) Correct the permissions for the directory ("if created above, in step
1")

 # chmod 755 /etc/polkit-1/rules.d

    3) Create a new file called /etc/polkit-1/rules.d/89-backlight.rules

 # vi /etc/polkit-1/rules.d/89-backlight.rules

    4) Add the following text to the new file called
'/etc/polkit-1/rules.d/89-backlight.rules'

polkit.addRule(function(action, subject) {
    if (action.id == "org.xfce.power.backlight-helper" &&
        subject.isInGroup("users")) {
        return polkit.Result.YES;
    }
});

    5) Correct the permissions on the file
'/etc/polkit-1/rules.d/89-backlight.rules'

 # chmod 644 /etc/polkit-1/rules.d/89-backlight.rules

    6) Edit the file
'/usr/share/polkit-1/actions/org.freedesktop.login1.policy' and change the
"backlight" rules to <allow_any>yes</allow_any>


I documented the fix on the wiki here:


https://wiki.debian.org/Xfce-power-manager-troubleshooting

And added a link the  xfce debian wiki page.

Maybe we can get these fixes incorporated into the package?

Thanks,
