System freezes for ~30s after login (SDDM?)

I recently upgraded my packages (pacman -Syu) and noticed that after I login or restart my system I get about a minute of "normal" system function followed by approximately 30 seconds of a (mostly) complete freeze. My cursor will still move around, but nothing else is responsive. I think I may have tracked it down to sddm or someting kde  related, but I'm not nearly certain about that. I found some very loud core dumps in journalctl (See this pastebin)

I'm not sure what steps I should take next.

System:

KDE Plasma 5.20.2
Kernel 5.9.1-arch1-1

Re: System freezes for ~30s after login (SDDM?)

Looks like some low level crash  in the graphics layer. Can you post a xorg log? If installed, remove xf86-video-intel and anything that might reference it and retry. If that doesn't help, tell mesa to fall back to the older OpenGL driver in a file that's sourced early like a drop-in to /etc/profile.d or so: https://wiki.archlinux.org/index.php/In … ver_(i965)

Yep, absolutely. When I get back to that machine later this evening, I'll do just that. Off the top of my head, I remember seeing some gtk_module failure, but I'll post the definitive output. Thanks for the response.

Alright, sorry for the delay. Here is my Xorg log.

I didn't have the xf86-video-intel installed. I also tried to set the env var as specified in the link, above, to no success.

Re: System freezes for ~30s after login (SDDM?)

That message reads scarier than it is and is often not relevant.

Nothing really conclusive here. Can you switch TTY's when the freeze happens? In any case maybe post a more complete journal

sudo journalctl -b-1 #If you were forced to reboot, omit the -1 if you can grab from a TTY during a freeze

... Only sidething, at least in that xorg attempt you are loading the iris driver, where did you add the override environment variable to?

Gonna be a bit before I can attempt the TTY switch and confirm that works. Though, I do recall being able to do so previously.

I had placed that env bar in my .xinitrc file and rebooted.

SDDM does not read your .xinitrc. If anything your .xprofile, if you want to be sure add it to /etc/profile

Re: System freezes for ~30s after login (SDDM?)

Alright. No success with placing the env var in my /etc/profile (even rebooted to be _extra_ sure). I attempted the TTY switch during the freeze and the only thing I got was a blinking cursor and no ability to type. So I'd call that a failure as well. Here's my journalctl -b output (I don't know why pastebin is marking that as offensive, btw). I noticed a few things in there...

Oct 31 21:45:11 arch sddm[419]: Failed to read display number from pipe
Oct 31 21:45:11 arch sddm[419]: Display server failed to start. Exiting
Oct 31 21:45:12 arch systemd-coredump[471]: Process 419 (sddm) of user 0 dumped core.
Oct 31 21:45:21 arch sddm-helper[583]: gkr-pam: unable to locate daemon control file

I'm sure there's other stuff in that output that is more clarifying, but those are the big red flags that stuck out to me. They all appear to be stemming from some sddm failure, but I don't know much about it, nor am I sure how to further debug it.

Hmmm...

Some investigating and it seems like it's probably a bug with gnome-keyring 1:3.36.0-1 as discussed here

Re: System freezes for ~30s after login (SDDM?)

Apart from that dump it seems to startup alright. The gkr-pam message is indeed normal and shouldn't be a cause for concern. I'd say try to use linux-lts or so to check if it's a regression in the kernel or/and an older mesa. Which packages and package versions were part of that update? Check your /var/log/pacman.log
