[SOLVED] Stuck on start up message "/dev/... clean" after upgrade

Hi,

So, today, I upgraded my Arch with

sudo pacman -Syu

and rebooted. After the startup, it started with the usual

Starting arch version...
/dev/... clean

thingy, but this time it's stuck. My cursor is visible and I can move it.
After searching for some times, I think my sddm or PAM is broken, but I'm not sure what to do.

My setup is:
Dual boot arch and win10
arch and win is on nvme ssd, /home is on hdd
Xorg, sddm, and KDE
Intel processor with integrated card plus nvidia dedicated

I went to tty2 to see journalctl,
Here is my

journalctl -b

output: http://0x0.st/obGX.txt

Please let me know if you need more log/output. Thank you very much for your help.

I think i got this temporarily solved for now
After hours of searching, I found out that this is a problem with the "mesa" package, downgrading it from 22.0.1-3 to 22.0.0-1 fixed the issue.

Do I just ignore "mesa" package on upgrade for now? I'm worried I might break other packages' dependencies or break my whole system if I ignore it

I'll reopen this issue until I get a permanent solution
Thanks

Re: [SOLVED] Stuck on start up message "/dev/... clean" after upgrade

You're crashing in the iris GL plugin on shader compilation.
This is a completely blind guess, but does it work when you globally (/etc/profile.d/somescript.sh)

export LD_PRELOAD=/usr/lib/dri/iris_dri.so

Hi,
I tried it and it's still stuck.

Could this be something related to this thread?
https://wiki.archlinux.org/title/SDDM#B … eter_shows
https://github.com/sddm/sddm/issues/1179
so the problem may be related to sddm?
Looking at /var/log/pacman.log, sddm got no update since I installed in on February
I also updated sddm-kcm on April 3rd, but the problem didn't occur.

EDIT: I tried switching to lightdm, and it's working with the latest mesa package

Re: [SOLVED] Stuck on start up message "/dev/... clean" after upgrade

Following from this thread:
https://bbs.archlinux.org/viewtopic.php?id=225464
that links to this thread:
https://bbs.archlinux.org/viewtopic.php?id=216223,

it turns out it has something to do with this "memory is full" part:
https://wiki.archlinux.org/title/SDDM#B … eter_shows

Blank screen with cursor, but no greeter shows
Greeter crashes if there is no available disk space. Check your disk space with df -h.

It's not my storage that is full, but I think the package cache.
So, I cleared ~/.cache and /var/lib/sddm/.cache, and sddm starts working again.

Re: [SOLVED] Stuck on start up message "/dev/... clean" after upgrade

The package cache is in /var/cache/pacman/pkg and can be cleared w/ "pacman -Scc"
If you're running out of disk space, you might want to consider that because the other caches will be rebuild pretty soon by sddm and the software you run (notably your browser)

If you're running out of disk space

Hi,
thanks for your reply

I still got hundreds of GBs left in my / and /home partition, so I don't think that's the problem.
Does package cache have it's limit itself? Independent of the disk space?

Re: [SOLVED] Stuck on start up message "/dev/... clean" after upgrade

No. Do you have a separate /var partition?
Otherwise I assume the problem was actually in some cached data from SDDM that got invalidated or fell incompatible w/ the updated version and needed to be rebuilt.

No, I don't.

Yeah, I conclude this too.
