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/65769is related, but looks like a hardware
issue?

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?

Thank you.

Cheers,

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:

Reverting Sway to 1.8.1 works.
