Subject: greetd-wlgreet-sway-session unable to login (Respawning term-tty1)
Date: Sat, 16 Mar 2024 10:47:23 +0000

It seems like `greetd-wlgreet-sway-session` broke for me, sometime in the last 
10 days. Initially I suspected it's related to my hardware, or a newer kernel, 
but I was able to rule these out with a clean config in the VM.
- It's working as of `3da49b1472919a62df1fe399638f23a246aa325d` (05.03) but does 
not anymore.
- On my working setup (05.03), I use logind; but I also tried seatd, without change.
- I suspected maybe Sway 1.9, but using the previous 1.8.1 did not help.
- Maybe https://issues.guix.gnu.org/65769 is related, but looks like a hardware 
issue?

```
(define-public sway-legacy
  (package
    (inherit sway)
    (name "sway")
    (version "1.8.1")
    ...))


(service greetd-service-type
          (greetd-configuration
          (greeter-supplementary-groups (list "video" "input" "seat"))
          (terminals
          (list
            (greetd-terminal-configuration
              (terminal-vt "1")
              (terminal-switch #t)
              (default-session-command
                        (greetd-wlgreet-sway-session
                          (sway sway-legacy)
                          (wlgreet-session
                          (greetd-wlgreet-session
                            (command (file-append sway-legacy "/bin/sway")))))))

            (greetd-terminal-configuration
              (terminal-vt "2"))
            (greetd-terminal-configuration
              (terminal-vt "3"))
            (greetd-terminal-configuration
              (terminal-vt "4"))
            (greetd-terminal-configuration
              (terminal-vt "5"))
            (greetd-terminal-configuration
              (terminal-vt "6"))))))
```

Here's a bunch of logs:

I'm a bit at the end of my latin, or guix, I guess.

Am I missing something that changed recently?
I'm mostly following https://guix.gnu.org/manual/en/html_node/Base-Services.html

Thank you.

Cheers,
Franz

New information always turns up, the minute after you submit the report. Thanks 
to a kind soul, I also found the greeter logs:

This is on:
- Libre kernel
- using logind
- Sway 1.9

Apparently this is a known issue: 
https://lists.sr.ht/~kennylevinsen/greetd/%3CCZEH2PTZ98MU.3UTOFBLK0R755%40pwned.life%3E

Reverting Sway to 1.8.1 works.
