[SOLVED] SDDM-Greeter segfault

Hello,

I'm contacting you because this morning I updated my system and since then it refuses to boot in graphics mode.

I'm using the classic Linux kernel and my system is fully encrypted. I have grub as bootloader and snapshots. I'm using KDE Plasma with SDDM. Also i'm using Nvidia driver (not "nouveau").

I have AppArmor enabled.

I am able to investigate in text mode :

journalctl -b -1

pam_access(systemd-user:account): access denied for user 'sddm' from 'systemd-user'

PAM failed: Permission denied
user@969.service: Failed to set up PAM session: Operation not permitted
user@969.service : Failed at step PAM spawning /usr/lib/systemd/systemd: Operation not permitted
user@969.service : Main process exited ...
Failed to start User Manager for UID 9691

...

sddm-greet segfault at ... error 4 in libc.so

Process 1086 (sddm-greeter) of user 969 dumped core.

A few other errors :

ACPI BIOS Error (bug) ...
ACPI Error ...
... (x3)

amd_gpio AMDI0030:00 Invalid config param 0014
amd_gpio AMDI0030:00 Invalid config param 0014
... (x 11)

hub 6-0:1.0: config failed, hub doesn't have any ports! (err -19)

[EDIT]

Full bootlog is here : http://0x0.st/Hpaw.txt

Disabling AppArmor change nothing...

Can you help me ?

[SOLVED]

Just remove LD_PRELOAD from

/etc/environment

Re: [SOLVED] SDDM-Greeter segfault

Please don't paraphrase, https://bbs.archlinux.org/viewtopic.php?id=57855
Please post your complete system journal for the boot:

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

Also see https://wiki.archlinux.org/title/Core_d … _core_dump

Please don't bloat the thread w/ full quotes.

août 31 14:51:27 mimahk systemd-coredump[1042]: Process 1023 (sddm-greeter) of user 969 dumped core.
                                                 
Stack trace of thread 1039:

#9  0x00007f548e710dfc n/a (libc.so.6 + 0x110dfc)

So the problem is in whatever libhardened_malloc.so you're using, possibly you'll just have to rebuild the AUR package.
Otherwise remove it or at least do not generally preload it.
