Power Manager issues

[xendistar]

Sometime ago I stopped using xscreensaver and swapped to putting the monitor to sleep after about 15 minutes (it always varied when I set it up or adjusted it, between 10 and 15 but never 13 minutes). At first this worked perfectly turning the monitor off and then coming back to life when I hit the keyboard of wiggled the mouse. Then it just suddenly stopped working, could see no reason for it stopping, and could not get it to function again, the monitor just stayed on.

Well last weekend after breaking my install I did a complete reinstall of 201808 SoldyX, once installed I went around tweaking the setting which included setting up the monitor to go to sleep and at first this worked perfectly, it even prompted me for a password to get back into the system which annoyed me but I could live with it until I had finished tweaking the rest of the install and get round to changing the settings. Then suddenly I noticed that the monitor was no longer going to sleep, I logged out as my user and back in again that made no difference, I rebooted the PC still not working.

Any suggestion where to look for this issue?

I'm on stable - you reinstalled EE, right? - but I just tried activating the power management and after being away for some time I'm seeing 2 login windows (one from lightdm and one from maybe xfce) and an error notification "GD.Bus.Error:org.freedesktop.DBus.Error.NoReply:Method call timed out".

This is a known error with Xfce Power Manager and lightdm: https://bugs.launchpad.net/ubuntu/+sour ... ug/1605189 which is supposedly fixed by setting "lock session automatically when screensaver is activated" in the security tab of XFCE power management to "never" - which is probably not a good idea in an corporate environment. I'll test this.

Another reported fix is adding /etc/polkit-1/localauthority/50-local.d/enable-suspend.pkla with this content:

Code: Select all

[Enable Suspend on Idle]
Identity=unix-user:*
Action=org.freedesktop.login1.suspend
ResultAny=auth_admin_keep
ResultInactive=yes
ResultActive=yes

I'm not sure whether this will fix your issue but stable needs fixing too so we should test both and see what happens.
Anything meaningful in your logs?

Code: Select all

Code: Select all

[Enable Suspend on Idle]
Identity=unix-user:*
Action=org.freedesktop.login1.suspend
ResultAny=auth_admin_keep
ResultInactive=yes
ResultActive=yes

IIRC this part should be already added in solydxk as default, along with enabling "no password" mount and other stuff. or perhaps I missed to suggest it?

[Arjen Balfoort]

/etc/polkit-1/localauthority/50-local.d/enable-suspend.pkla is not part of the system-adjustments packages.
There's no polkit configuration for "no password" set either (did I miss something?).

Let me know if I need to add it.

[xendistar]

Before I go any further a point of clarification, all I am trying to do here is to blank my monitor after X minutes, (see XFCE power management window, display tab), I am not trying to suspend the PC or put the PC to sleep.

ilu
Yes I am running EE, I had a look at my logs (I used xfce4-power-management as the search phrase) and I only got one hit. I stopped using the PC and went out at 16:40 and did not return until 18:20, but the hit shows the time as 17:30 My blank monitor is current set for 15 minutes which means it should of blanked the screen at 16:55 (approx).

Code: Select all

As Arjen states that he has not installed Polkit, I have not investigated that area.

A question, as a lot of this seems to be related to LightDM, what exactly does it do and do we really need it?

[kurotsugi]

we need lightdm at least for two thing: login into our system and secure our system from unauthorized user. it doesn't have to be lightdm but lightdm has several benefit compared to other login manager. the main problem was, debian is tend to lean towards servers, where a pretty login manager is not needed and headcost performance is kept as low as possible.

it also about security. the tweak above will allow "a software" to lock the session without user manually lock it. the problem is that it would create a security risk --as you guess it-- for servers. OTOH, desktop realm is quite different with server one. contrary to the server, I believe this tweak will enhance our system security.

/etc/polkit-1/localauthority/50-local.d/enable-suspend.pkla is not part of the system-adjustments packages.
There's no polkit configuration for "no password" set either (did I miss something?).

Let me know if I need to add it.

IMO absolutely yes. the "no password" stuff should be this one

Code: Select all

[Password-less mounting of local partitions]
Identity=unix-group:users
Action=org.freedesktop.udisks2.filesystem-mount-system
ResultAny=yes
ResultInactive=yes
ResultActive=yes

Action=org.freedesktop.udisks2.filesystem-mount
ResultAny=yes
ResultInactive=yes
ResultActive=yes

Action=org.freedesktop.udisks2.filesystem-mount-other-seat
ResultAny=yes
ResultInactive=yes
ResultActive=yes

IIRC we have this tweak along with several other polkit tweaks. I already have ilu's tweak and my system so I thought it already included in our tweak. though, honestly I can't recall when did I added it into my system. the bug might only happened on EE and I forgot to report this issue.

[xendistar]

Thanks for the explanation Kurotsugi, reading your post I suddenly remembered GDM & KDM to name but two other desktop managers. I guess at the end of the day I could change to another Display manger (https://wiki.debian.org/DisplayManager) but at the moment I thing that is a bit drastic.

Arjen, is it possible to add the polkit to the system-adjustments package but have it in a off state as I would hate to have it added and then everybody else gets an issue because of its additions. Once added then I can make it active and test the setting offered by Kurotsugi, ilu and the web link?

[Arjen Balfoort]

@kurotsugi
Thanks! I've added these pkla files to the solydx/k-system-adjustments packages (both solydxk 9 and solydxk 10):

Code: Select all

/etc/polkit-1/localauthority/50-local.d/91-password-less-mounting.pkla
/etc/polkit-1/localauthority/50-local.d/95-enable-suspend.pkla

Let me know if this is alright.


@xrendistar
I've uploaded the packages to testing. So, it's not needed to disable anything. You just need to adapt your /etc/sources.list file so that the solydxk line contains "testing":

Code: Select all

deb https://repository.solydxk.com solydxk-9 main upstream import testing

After an "apt update" you can install the solydx-system-adjustments-9 package (rename to your version).

[xendistar]

Added the following line to my source list

Code: Select all

deb https://repository.solydxk.com solydxk-10 main upstream import testing

Ran an update and got this error at the end

Code: Select all

[Arjen Balfoort]

I see that you don't have the solydxk-system package installed.

I've updated the solydx/k-system-adjustments packages so that it checks for the existence of the adjust.py script.

Could you update the package again?

[Arjen Balfoort]

Yes, now you can try out the new polkit configuration.

[xendistar]

<snip>

Another reported fix is adding /etc/polkit-1/localauthority/50-local.d/enable-suspend.pkla with this content:

Code: Select all

[Enable Suspend on Idle]
Identity=unix-user:*
Action=org.freedesktop.login1.suspend
ResultAny=auth_admin_keep
ResultInactive=yes
ResultActive=yes

<snip>

I have checked enabled-suspend.pkla and it has the setting that ilu posted earlier (as above) there are no other entries in the pkla file. Now when I leave the PC the whole PC goes into suspend mode and does not come back to life, resulting in having to push the button on the PC, this is not what I wanted. How do I remove the polkit setting as I don't want my pc suspended, can I simply remove all the lines in enable-suspend.pkla??

When I first installed SolydX, the monitor would switch off after 15 minutes using the XFCE Power Management (Display) tab and setting the Blank to 15 minutes, put to sleep never, switch off after to never. This worked for a couple of day until I rebooted the PC (this PC runs 24\7) upon rebooting the PC, the monitor was never blanked despite the setting still being the same.

[Arjen Balfoort]

Remove "testing" from your sources.list and run these commands:

Code: Select all

apt update
apt install solydx-system-adjustments-10=2.9.8

This will downgrade your version to the main version and remove the new pkla files.

[xendistar]

OK did that but then got the same sort of error when I first tried to install the polkit

I ran

Code: Select all

dpkg --configure -a

and got the following

[Arjen Balfoort]

Ah yes, because you don't have solydxk-system installed.

It's now either install the version from testing and delete the pkla files you don't want (but they will be reinstalled if there is consensus on keeping them) or install solydxk-system.

[xendistar]

I am not sure why I have no solydxk-system as I simply did a normal install, I assume it is part of the normal install? Where can I download it from? I will keep the file but just remove all entries and see how we get on with that.
