[Bug 1795637] Re: No login screen when booting Cosmic

[Iain Lane]

I've uploaded a pkg to cosmic unapproved which contains
https://gitlab.freedesktop.org/plymouth/plymouth/commit/85d843af843589ce8538a59e5cb665b8253e380d
amongst a few other cherry picks that are worthwhile to have in cosmic.

--- details unrelated to this bug (boot race with plymouth & DRM) ---

I know this isn't the end of the story with regard to boot races
(there's a "Could not find primary drm kms device" thing that Trevinho
is looking into), but it gets us closer.

Possibly we should use a new bug for that other problem so this one
doesn't get confusing with multiple fixes for a broad symptom.

(If so, please file it, rls nominate it, attach the journal logs that
show the bug happening so it's clear it's about that problem and no
other and assign to Trevinho)

** Summary changed:

- No login screen when booting Cosmic
+ No login screen when booting Cosmic due to plymouth racing with the rest of the boot process and not releasing DRM devices in time

** Changed in: gdm3 (Ubuntu Cosmic)
       Status: Triaged => Invalid
