<pre>All the components here are way out of my expertise, but I think there are two
different issues:
- if weston fails in any way, it really shouldn't leave the VT (or kmscon)
broken, especially when usind weston-launch where the VT handling is external
to weston itself. (Might also be an issue with kmscon, not just weston or
weston-launch).
- weston fails to begin with
I know little about systemd and logind, but is the shell inside kmscon in a
real user session (in systemd/logind terms)?
Does kmscon take DRM master? If yes, that means Weston cannot take it, and KMS
calls will fail. Maybe that is the main issue.
Unfortunately I have no idea how an app that wants to be a DRM master should
run under something like kmscon.
I'm adding David Herrmann to CC. Maybe he could explain how things are supposed
to work between systemd, logind, kmscon, weston-launch, and weston.
Btw. IIRC Sysrq-v is a thing that should forcefully restore fbcon, but I've no
idea what it might do to kmscon.</pre>
