Pantheon session crash after lock or suspend with multi-monitors #60082

davidak · 2019-04-23T09:57:46Z

Issue description

I have this problem on a Lenovo Thinkpad L470, but not on a Thinkpad X230 or custom gaming PC.
I had issues with X11 sessions before on this device, see #44344.

See the log full of errors: https://gist.github.com/davidak/d2de7f9ef515755db76f3b61b102b664

And video: https://peertube.social/videos/watch/2c9d8be7-3adb-48ae-a874-799fd9804dd2

Steps to reproduce

lock or suspend session
when locked, the screen get on again after 2 seconds

i can't type in password field, only click on "login" without password. it is wrong obviously
then i can type in a password again and get a new session. my former session is crashed

Steps 3-5 look exactly how a crash in a session would look like, also assuming you're using the default gtk LightDM greeter.

But these logs look like X died took everything with it.
Can you get a stack trace from coredumpctl or maybe something from the Xorg logs?

davidak · 2019-04-23T11:37:40Z

correct

Can you get a stack trace from coredumpctl

i try to get one

or maybe something from the Xorg logs?

journalctl -u display-manager.service

davidak · 2019-04-23T12:29:07Z

I tried to enable core dumps, but the documentation is not clear how to do. #60088

I don't get coredumps after applying the changes and rebooting.

But when locked, the system don't reacts on keaboard input, mouse or touchpad interaction. Only clicking the power button let the device shut down.

Suspending still let the session crash. But no core dump.

worldofpeace · 2019-04-23T13:01:49Z

Have you tried switching to a tty with the shortcut?

Also, when having issues with locking and suspending, it could be two independent issues so I'd need to know

how exactly a session is locked
how it was suspended
how it's unlocked
how you resumed

worldofpeace · 2019-04-23T13:06:39Z

Edit: saw the video, (felt the frustration 😄) and going with debugging locking specifically where
it's locked with the shortcut and no keyboard input needed to wake (by itself)

That's a multi-monitor setup if I'm not mistaken?

davidak · 2019-04-23T14:40:09Z

That's a multi-monitor setup if I'm not mistaken?

yes. it's a thinkpad on a docking station with 2 external displays.

this strange thinkpad has also a dedicated radeon GPU, but it has worse performance than the integrated intel gpu when open source drivers are used, so it's ok it is not used. but that might also cause trouble...

Have you tried switching to a tty with the shortcut?

that works. then i can also go back and login again, to a new session.

how exactly a session is locked

shortcut or menu in upper right

how it was suspended

menu

how it's unlocked

only way is to go to a tty and back to tty 7, then you can login

how you resumed

when hit ENTER, the login screen appears. again login 3 times to new session. moving and clicking mouse does nothing

worldofpeace · 2019-04-23T14:46:57Z

✨ I can reproduce steps 3-5 with a multi-monitor setup.

I tested that with a laptop with Intel UHD Graphics 620. Strangely enough though, if you use the pantheon greeter you cannot unlock a session with multi-monitors. Which in a way prevents the session from being killed altogether.

davidak · 2019-04-23T14:49:44Z

I have a Intel Corporation HD Graphics 620 (rev 02) too.

davidak · 2019-04-23T15:07:06Z

I can confirm that unlock and resume works without external displays.

When trying to unlock, the display still remains dark. I have to go to a tty and back to tty 7, multiple times.

Same when bootet without external displays.

Now i saw the "This session is locked" when i go back to tty 7, some seconds later i get the login screen.

That sounds exactly like the-cavalry/light-locker#138
so an issue with light-locker (probably a regression from GNOME 3.30?).

Edit: sounds like light-locker can't switch back to the greeter properly

davidak · 2019-04-23T15:53:02Z

so an issue with light-locker (probably a regression from GNOME 3.30?).

in gnome on NixOS 18.09 i had no issues with locking (with GDM! with lightdm locking probably still don't work). but with Xfce earlier, that's why i switched to gnome... #38493 (Xfce uses xflock4)

That sounds exactly like the-cavalry/light-locker#138

yes, except

I get a message that the screen is locked and I get redirected to unlock in a few seconds but that never happens

i got the login screen in about 2 seconds

davidak · 2019-04-24T12:56:50Z

I can now say that there are no core dumps.

Did you have some success with debugging? Can i help in some way?

worldofpeace · 2019-04-24T13:03:22Z

I'm looking for time to debug, as it's going to be interesting and involved.
From there I'm suspecting that we'll need the co-operation of upstream to actually fix the issue.

And you're and have been very helpful btw

davidak · 2019-05-05T02:34:56Z

Next step is to get a backtrace with gdb of the gnome-session-binary --session=pantheon process.

https://wiki.gnome.org/Projects/GnomeShell/Debugging

davidak · 2019-05-06T18:28:22Z

I tried Obtaining a stack and JS trace using GDB for an already running gnome-shell

sudo gdb -p $(pgrep -U $USER gnome-session) -batch   -ex "set logging on" -ex continue   -ex "bt full" -ex "call gjs_dumpstack()"   -ex quit

but i only got:

[davidak@ethmoid:~]$ cat gdb.txt

(I locked the screen, tried to unlock but screen was dark no matter what i did. after hitting the power button the system shut down)

davidak · 2019-12-06T14:38:01Z

I'm using my Thinkpad X230 with 1 external display connected via VGA right now and don't have this problem.

So the cause might be the other hardware (it has hybrid graphics) or 2 displays (using docking station.)

I will try to test with a desktop computer and more than 1 display.

worldofpeace · 2019-12-06T18:18:36Z

@davidak Pantheon has made some moves to use latest mutter, ref #73906.

worldofpeace · 2020-04-01T21:28:18Z

I tried this out with #73906, and I can't reproduce this issue anymore. But switchboard-plug-display needs to be updated for latest mutter.

davidak · 2020-04-02T01:36:31Z

Great. I'm currently in homeoffice and don't have a docking station or multiple monitors here, so i will not be able to test it for some time...

But i put it on the list of tasks to do at the office.

Thanks. It will be merged to nixos-unstable once staging-next gets merged #83618.
