light-locker is broken on Juno #92

light-locker not working
please help me
Juno Beta

danirabbit · 2018-03-25T21:17:47Z

Unless you're a time traveler, you're certainly not running Juno Beta. Can we get your actual system information please? If you're installing development packages on another operating system, you should not expect to have a working system.

Closing as "incomplete"

I'm also experiencing this with an alpha build.

codygarver · 2018-03-26T15:52:14Z

Since we started using light-locker years ago I had to create a DPMS daemon to set values that light-locker expects/requires. However, it requires a patched GSD.

Since components are getting upstreamed to other distros, this has become a point of controversy.

I would like a cleaner way to accomplish the same goal but I have no idea what that is. I am holding off on "fixing" this bug for as long as possible.

Patched GSD: https://bazaar.launchpad.net/~elementary-os/elementaryos/os-patch-gnome-settings-daemon-xenial/revision/2

decathorpe · 2018-05-08T12:14:54Z

Yeah, it would be nice to have a working screen lock without having to rely on gnome-settings-daemon patches (which I can't do on fedora, for example).

codygarver · 2018-05-11T10:16:59Z

Fixed by elementary/session-settings@b0e7a28 and elementary/os-patches@af897c5 and elementary/os-patches@6975d1c

decathorpe · 2018-05-11T12:04:25Z

Is there a way I can fix light-locker without having to patch gnome-settings-daemon?

btd1337 · 2018-05-20T03:42:10Z

How to get this fix?

btd1337 · 2018-05-27T06:00:23Z

This hotfix was it released? Because this error persists.

@codygarver Screen is not Locking for me either

stradicat · 2019-01-15T00:13:01Z

Still happens in Juno release.
Fresh install, from scratch.

peteruithoven · 2019-01-15T00:20:18Z

@codygarver any idea why people might still be experiencing this issue?

codygarver · 2019-01-15T00:51:45Z

One situation where this can happen is if gnome-screensaver gets installed somehow, usually as a dependency of something else like ubuntu-unity-desktop or budgie-desktop. Try sudo apt-get remove gnome-screensaver and reboot if it was present.

stradicat · 2019-01-15T02:25:11Z

Hello Cody,

none of those packages are installed.

This happens on a fresh Juno install, no extra packages added. I downloaded the .ISO 2 days ago from the elementary site, so the version is up to date.

I tried once with the nvidia binary drivers I normally use; then reinstalled just using the nouveau driver, thinking about dpms having something to do, somehow.

Problem persisted on both cases.

codygarver · 2019-01-15T18:49:35Z

Just to be certain, you're experiencing this error message, right?:

$ light-locker-command --lock
** Message: 05:51:43.183: Received error message from the locker: GDBus.Error:org.freedesktop.DBus.Error.ServiceUnknown: The name org.freedesktop.ScreenSaver was not provided by any .service files

Can you post a log of your installed packages?:

apt list --installed > installed.txt

It seems like something is preventing the lock from being possible, according to the error message, instead of being missing DPMS settings that set the timeout.

stradicat · 2019-01-15T18:54:00Z

I'll check the logs tonight, as there's no message displayed, along with my currently installed packages.

Bear in mind that this happens with the default Juno installation, with or without additional system updates, restricted extras, and/or system updates (I've already tested all these scenarios by reinstalling from scratch, formatting partitions each time).

My machine is a ThinkPad T410s (1st. gen i5 @ 2.53Mhz, Nvidia NVS3100M, 4 GB RAM).

stradicat · 2019-01-15T23:35:24Z

As requested, installed.txt.

Since I needed to get some work done, I had to install packages and remove light-locker to avoid locking myself out of work again.

stradicat · 2019-01-15T23:41:06Z

About the error message:

I reinstalled light-locker and tried your command:

$ light-locker-command --lock
** Message: 20:38:53.425: Received error message from the locker: GDBus.Error:org.freedesktop.DBus.Error.ServiceUnknown: The name org.freedesktop.ScreenSaver was not provided by any .service files

It's the same message.

codygarver · 2019-01-17T20:44:57Z

Hrm, I don't see anything obvious in the installed packages that could be breaking this.

I'm curious what hardware others who are experiencing this issue have.

In the meantime, I recommend you write an email payment@elementary.io and ask for a refund.

stradicat · 2019-01-19T16:58:19Z

I'll leave my hardware specs here, it may help pinning down the problem cause.

pridumkuvatyj · 2019-03-27T15:54:48Z

@codygarver, I also have the same situation with locker. My system is a bit littered(I've been trying gnome-desktop), but gnome-screensaver is removed. Anyway I couldn't lock the screen on a fresh Juno release install too. Attaching my hardware list also if it helps.
Thanks!

The problem occurs while I'm using the nvidia-340 proprietary driver (version 340.107); the open-source nouveau driver doesn't cause this problem, but its performance is a no-go for the purpose of this laptop, so I need to stick to the former.

GPU is an NVidia NVS3100M

worldofpeace · 2020-03-30T18:17:48Z

Is this still an issue? It seems very stale (@tintou maybe you could close this)

stradicat · 2020-03-30T21:49:32Z

There are 2 problems I'm still experiencing while using the nvidia-340 driver:

1.- Locking the screen brings the user back to the login screen, right? Well, that login screen is at a lower resolution than the desktop's, as if somehow it weren't the original light-locker instance.
2.- I can't lock screen and log into another user account; entering the password brings a brief black screen, then goes back to the login screen (with the glitch described above). I have to log out completely from the current user account before logging into another.

If this behavior should be described in another ticket, I can do so.

Thanks for looking into this! 😄

Thanks. All of that sounds different than the op. It also seems they're considering replacing light-locker, but depending on the severity of the issues they could issue a bugfix still.
I think you should open new issues.

stradicat · 2020-04-06T17:28:03Z

@worldofpeace Will do. Thanks for looking into it!

cassidyjames · 2020-04-06T17:46:30Z

Closing as we've not had recent reports that match this issue, plus we've had significant greeter and session changes since it was reported. New issues can of course still be reported or this one can be re-opened if it's still relevant.

stradicat · 2020-04-06T18:39:00Z

Ok, as per @worldofpeace's suggestion, I've opened a related ongoing issue with the current greeter
#422

bubersson · 2020-10-02T04:09:25Z

I'm getting the same error now when clicking on the lock button or when using keyboard shortcut.

Here's some debug info:

During restart I get

                                        This probably reflects a bug in the program.
