nixosTests.lightdm hangs

[vcunat]

The test hangs since the last staging-next iteration, after the "TIFF conversion" error got fixed. The nixos-unstable channel depends on this.

I've tried also on a couple other (idle) machines, so the issue doesn't look transient.

Did you bisect the commit already? If not, I'll do.

I haven't tried this one. You'd also need to keep applying #375091 as needed.

In any case, bisect still running.

In my testing this was fixed by #375504
