Description Oliver Schramm 2026-01-26 14:04:28 UTC

SUMMARY
Due to some "fun" shenanigans my root filesystem (/home is unaffected) currently only mounts as readonly on boot. After login, the splash screen doesn't disappear, and I have to manually kill it via Ctrl+Meta+Esc.

STEPS TO REPRODUCE
1. Inhibit remounting root as rw on boot
2. Login after dismissing SDDM’s warning that it could not write to some path

OBSERVED RESULT
The splash screen appears, the cog stops spinning and disappears, but the splash screen remains.

EXPECTED RESULT
The splash screen goes away as normally.

root system readonly can't be sole the trigger since there are OS where / is r-o and ksplash hides correctly.

Comment 2 Oliver Schramm 2026-01-27 10:55:43 UTC

Isn't there only /usr read-only? /var and /etc are surely still writeable there?

Comment 3 David Redondo 2026-01-27 11:16:35 UTC

Right, however I would not expect the splash having to write to /etc but maybe indeed /var

Comment 4 Nate Graham 2026-01-30 17:29:05 UTC

Any chance you can find out the exact write it's being blocked from making?
