--- Comment #2 from Oleksandr <[email protected]> ---
Clarification on the report: there is **no crash**, so no backtrace or coredump
exists —
`coredumpctl list plasmalogin-helper` returns *No coredumps found*, and
`systemctl status plasmalogin` after reproduction shows the service `active
(running)`,
started cleanly (`ExecStartPre` → `code=exited, status=0/SUCCESS`).

The summary describes the **recovery state**, not the defect. The actual bug:

- Restarting `plasmalogin.service` leaves a **black screen on the active VT**.
- The greeter *does* start, but only renders on a **secondary VT** (reachable
via Ctrl+Alt+F2).
- Switching back to the original VT returns to the black screen — it is never
reclaimed.

So the greeter process starts correctly but **never takes over the active VT**
after a
service restart. This is a VT/session-handoff issue, not a crash, which is why
the standard
"attach a backtrace" workflow doesn't apply here.
