Gnome+Wayland random logouts

Hello All,

As a recent windows-hopper I am very happy with Arch (after flirting with debian on older machines before). These are the specs of my PC:

  • Ryzen 7 1700

  • Asrock B350m Pro 4

  • 16 GB RAM

  • RX480 8GB

  • Sata SSD

The system runs fine, but seems to be logging out randomly sometimes. I am suspecting it has something to do with firefox, but I'm not sure what to do next. I run an up-to-date arch with gnome on wayland. After it logged out again I was able to get the following from the journalctl ( Pastebin ). I am using GNOME + GDM

What I tried to do:

  • Use linux-mainline package from AUR, since I was expecting maybe the ryzen updates + fixes in radeonSI would maybe help. (4.12rc2)

  • googling parts of my journalctl, however I could not find any usefull information

  • Using other browser, but also with chromeium it random logs out

  • Use X11 instead of wayland, also had log outs

My question for you guys

  • What exactly is the culprit for this? libgs, browser or something else?

  • Are there any known bugs that I missed?

  • What can I do to solve this issue? Any more debugging I should do?

Thank you guys in advance! In the mean time I keep -Syu'ing hoping for fixes..

Can you find the coredump info of PID 19788 using `coredumpctl info 19788`?

Can you find the coredump info of PID 19788 using `coredumpctl info 19788`?

I get "no coredumps found" with that command, probably because I already started a new session? Would that have the same information as the stack trace within the log?

No coredumpctl is not connected to sessions. (# means run as root / use sudo)  Does the following list any coredumps?

# coredumpctl

# coredumpctl

sudo coredumpctl gives output
the info <pid> does not result output. However within the logs I posted there is (line 112)

May 24 00:53:46 ArchDesktop systemd-coredump[19789]: Process 972 (gnome-shell) of user 1000 dumped core.

Is that what you mean?

EDIT:

Re: Gnome+Wayland random logouts

Is the output of `sudo coredumpctl` the same as the output of `coredumpctl` I am wondering if your user is prevented from seeing some output from coredumptctl
From the coredumpctl man page

man 1 coredumpctl wrote:

       Example 3. Show information about a process that dumped core, matching
       by its PID 6654

           # coredumpctl info 6654

PID 19788 is the first crash listed in the journal excert,  972 is later so may be the result of the first crash that is why I was more interested in 19788.

Re: Gnome+Wayland random logouts

The output of 'sudo coredumpctl' and 'coredumpctl' are the same. This also means that I cannot find the coredump for pid=19788 sad

So does this mean that the issue is related to firefox?

Re: Gnome+Wayland random logouts

No. gnome-shell uses the mozilla ecma engine as its scriting language (because a display & session server should always have the most complex design ...)
This is likely related to some extension/applet you're running - anything non-stock is suspicious.

There's also https://bugs.archlinux.org/task/53983 (one attachment has a matching backtrace) and that points https://bugs.archlinux.org/task/53582
