            Bug ID: 95186
           Summary: VT-switching on fbdev-backend goes unnoticed with
                    logind
           Product: Wayland
           Version: unspecified
          Hardware: Other
                OS: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: weston
          Assignee: wayland-bugs at lists.freedesktop.org
          Reporter: ppaalanen at gmail.com
                CC: dh.herrmann at gmail.com

Using a systemd system with logind, DRM-backend works just fine with
VT-switching, responding with device_paused() and device_resumed() on the DRM
device.

On fbdev-backend, VT-switch away from Weston does happen, but Weston is not
notified about it at all. This leads to Weston painting over a VT not its own,
and probably still getting input, etc. Switching back to Weston's VT freezes
the VT completely, until Weston is killed. Killing returns the VT back to
normal.

parse_active() never gets called, and indeed property_changed() is never
called.

All these functions are in src/launcher-logind.c.

Presumably the rpi-backend suffers the same, did not test.
