[SOLVED] Coredump libglib 2.0 at boot

Last -Syu broke my booting process. Chrooting tells me something's wrong with gnome and libglib 2.0:

Oct 21 13:17:51 xps13-fpierreh systemd-coredump[2193]: Process 2178 (gnome-session-i) of user 1000 dumped core.

Re: [SOLVED] Coredump libglib 2.0 at boot

1. Don't post pictures of text, post the text
2. get a swiffer?
3. the important bits are missing, please post your complete system journal for the boot:

sudo journalctl -b | curl -F 'file=@-' 0x0.st

But it kinda looks like youlikely do https://wiki.archlinux.org/title/GDM#Use_Xorg_backend - which doesn't work w/ gnome 49 (and yes, gnome shell "should" be aware of that and not crash and it most certainly "should" not try to fall back to X11 when wayland doesn't wok…
4. alternatively you might hit https://bbs.archlinux.org/viewtopic.php … 5#p2263495 (and GDM trying to fall back to X11)

Edit: fuck. I mean "five": please also don#t embed oversized images, the board has a 250x250 max rule to prevent threads from turning into scroll-fests.

Re: [SOLVED] Coredump libglib 2.0 at boot

journalctl -b

has no entries.

journalctl -p err | curl -F 'file=@-' 0x0.st

journalctl -b -1 | curl -F 'file=@-' 0x0.st

/etc/gdm/custom.conf

has

#WaylandEnable=false

Uncommentting does not seem to affect the outcome.

/etc/nsswitch.conf

  is properly set (shadow: files systemd).

Re: [SOLVED] Coredump libglib 2.0 at boot

https://0x0.st/KjCD.txt ends abruptly and before reaching even the multi-user.target.
Don't reboot w/ the power button - you can most likely just switch the VT (ctrl+alt+f3) and login

If "sudo journalctl -b" has "no entries", what produced the backtrace you edited in #1 - OCR??
Edit: resp. how did you even get to see it on the original photo?

I can't the keyboard is unresponsive after the crash.

journalctl -b -1

But indeed, last boots stopped showing the original coredump. I can't explain it.

Re: [SOLVED] Coredump libglib 2.0 at boot

Can you reboot w/ the https://wiki.archlinux.org/title/Keyboa … el_(SysRq) (+REISUB)
Can you boot the multi-user.target (2nd link below)?
Does an older boot like

sudo journalctl -b -3

still have the original coredump?
(The precise boot doesn't matter - just the information about the crash)

Re: [SOLVED] Coredump libglib 2.0 at boot

I removed my systemd autologin and managed to handle things without chrooting (complete crash was due to repeated autologin attempts I suppose). The requested log from the main user (where you'll see the coredump):

sudo systemctl -b

multi-user.target doesn't solve the issue.

Re: [SOLVED] Coredump libglib 2.0 at boot

Ah, you're "manually" autostarting gnome - most likely "wrong" (because the wiki suggestion is long-time contested as "doesn't work at all")
=> https://bbs.archlinux.org/viewtopic.php … 3#p2268463

That aside, disable dhcpd if you're gonna use NM.

Neither will explain your keyboard failure, though.
I'll have a close look at the journal but please check and report whether that problem is gone after fixing gnome.

Edit:

oct 21 17:33:45 xps13-fpierreh (udev-worker)[1727]: 3-1.1:1.2: Process '/opt/displaylink/udev.sh /dev ' failed with exit code 2.
oct 21 17:33:45 xps13-fpierreh colord[1839]: Error my backend :        out of memory

But the keyboard is i8042 - not sure whether the usb udev rule or the OOM colord (both likely caused by the failing gnome session) could impact tha.

oct 21 17:31:13 xps13-fpierreh kernel: spi-nor spi0.0: probe with driver spi-nor failed with error -22

That's the broadcom wl driver - is this a regression or has that chip never properly worked?
My first instinct would be to

oct 21 17:31:14 xps13-fpierreh NetworkManager[906]: <info>  [1761060674.9674] device (wlp2s0): set-hw-addr: set MAC address to 52:C6:EB:2B:73:43 (scanning)

disable that, https://wiki.archlinux.org/title/Networ … domization

Re: [SOLVED] Coredump libglib 2.0 at boot

No: I autolog with systemd and then autostart X in bashrc and gnome in xinitrc.

I followed your suggestion but to no avail.

I commented the autostart of X. Starting it manually shows the server shutting down immediately with a failure in enabling I/O ports (permission errors).

Re: [SOLVED] Coredump libglib 2.0 at boot

That will under no circumstances work because gnome v49 no longer supports X11.

If you want to start gnome (on wayland) w/o a DM see the approach in the other thread.

Re: [SOLVED] Coredump libglib 2.0 at boot

Thank you I totally missed that.

My solution: I kept autologin through systemd, enabled GDM and set autologin to True in GDM conf.

Regarding the wpa_supplicant error, I ordered a new network card to bypass Broadcom proprietary drivers which are probably the reason of those failures. I indeed can't get wifi networks anymore.
