problems with light-locker

Hello all of you out there on the forum,
I'm having and issue with light-locker on my Gentoo build,
When I try to execute it I get these messages:

Code: Select all

(light-locker:5020): dbind-WARNING **: 00:44:02.970: Couldn't register with accessibility bus: Did not receive a reply. Possible causes include: the remote application did not send a reply, the message bus security policy blocked the reply, the reply timeout expired, or the network connection was broken.

** (light-locker:5020): ERROR **: 00:44:02.970: session_id is not set, is /proc mounted with hidepid>0?
Trace/breakpoint trap

I tried mounting proc with a diferent hidepid setting but it doesn't seems to work,
I didn't setup any different USE flag on lightdm or light-locker, and the --debug option throws me the same.
What can it be?.
Thank you very much y'all.

Hi kuipumu,

if you are using consolekit and light-locker-1.9, then downgrade to version 1.8 and everything should be fine.
The dev removed support for consolekit in version 1.9.

Is this the only solution? Just asking because if so I will mask version 1.9.0 (I like light locker) but I'd imagine that cannot work forever. I somehow got version 1.9 to work on a couple of my workstations but now it seems to be having problems on several others.

Are you sure it doesn't have something to do with the first warning? Is this a `dbus` warning?

Hi sgdavis,

I had the same problem some time ago and spent a whole day figuring out what went wrong. With elogind everything OK, but with consolekit i got the same messages as kuipumu. The only solution was a downgrade.
I also like light-locker, but without support for consolekit, i will switch to xfce-screensaver and its built-in lockscreen.

I am not really sure, but i think the first warning means that light-locker (1.9) cant connect to dbus.

The changelog can be found here:

Posted on an Issue thread. Looks like this has already come up over there but maybe we can get some insight from the devs about why they made this decision...

They probably took that decision because the original ConsoleKit code has not be touched since July 2013:

likely be the final release. You are advised to switch to logind:

http://www.freedesktop.org/software/sys ... rvice.html

and ConsoleKit2, the fork that is used in Gentoo, has not been touched since December 2017:

https://github.com/ConsoleKit2/ConsoleKit2

Basically, ConsoleKit is obsolete. Gentoo also provides the actively-maintained elogind as an alternative to ConsoleKit. I didn't have to make many adjustments when I migrated from ConsoleKit to elogind a year ago on both my Gentoo installations (one is amd64, the other ~amd64):

Yup I got them to confirm that over on the github page. However, in my digging around I am not actually convinced that consolekit is the problem. It looks like they are still using "dbus-glib" also deprecated and needs to be replaced with GDBus.
https://developer.gnome.org/dbus-glib/unstable/

It is weird though because it almost looks like they half ported the code already. The `light-locker-command.c` code looks to use GDBus where as `gs-dbus.c` seems to use both dbus-glib and even older dbus code. SO, I think that is what needs to be changed. Weird that they removed one deprecated system but not the other...

So do you think this might work? I'm not using systemd yet and I am not sure I am ready for that switch, can I still switch over to elogind?

you're right, but not everyone wants systemd or parts of it on his machines.

Ummm, notice anyone familiar?

Lennart Poettering was the maintainer of the original ConsoleKit:

ConsoleKit is no rose.

Yes you can. That's what I did in both my Gentoo installations (one Stable, the other Testing).

elogind is an independently-maintained fork of (only) the logind component of systemd. Both my Gentoo installations use OpenRC+elogind. I converted both my Gentoo installations from OpenRC+ConsoleKit to OpenRC+elogind a year ago. The impetus in my case to finally make the switch was that Microsoft made Skype for Linux dependent on logind

. Since I don't have systemd in my Gentoo installations (USE="-systemd" in /etc/portage/make.conf) and have no intention of installing it either, I migrated to elogind so that Skype for Linux will work in Gentoo on my laptops. Other than a couple of minor changes mentioned in my previous links, I have not noticed any difference since migrating. And with elogind Wayland works in KDE on my main laptop (albeit I have no particular need or wish to use Wayland).

Gentoo Wiki wrote:elogind is the systemd project's logind, extracted to a standalone package. It's designed for users who prefer a non-systemd init system, but still want to use popular software such as KDE/Wayland or GNOME that otherwise hard-depends on systemd.

Ok for anyone reading along -- this is the perfect solution. ~20 packages recompiled with the new USE settings (-systemd -consolekit elogind) and then just shutdown xdm, restart dbus, and startup elogind+X, and BOOM. light-locker is working again!

Thanks for all the help. It is nice to clean up that abandoned project from our systems too (emerge --depclean consolekit). I didn't even have any blips with the switch. It just worked. Gotta love it when that happens.

I don't care about Lennart Poettering, I also use pulseaudio, but I don't want to have systemd nor parts of it on my PCs.

That's what I mean and it's getting worse. Systemd everywhere, except BSD.
