From 5a2d5dbdf8c6f6d3c896082a5a07b4292f5fb410 Mon Sep 17 00:00:00 2001

Subject: [PATCH 1/2] meson: set -D_GNU_SOURCE for updwtmpx
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Without setting GNU_SOURCE, we end up getting:
```
../gdm-42.0/daemon/gdm-session-record.c:200:9: error: implicit declaration of function ‘updwtmpx’; did you mean ‘updwtmp’? [-Werror=implicit-function-declaration]
updwtmpx (GDM_NEW_SESSION_RECORDS_FILE, &session_record);
```
This ended up exposing a bug in updwtmp(3) (which is now fixed
thanks to the man-pages maintainers!) as it didn't mention that updwtmpx
is a GNU extension (and hence needs GNU_SOURCE in order to be available).
Alternatively, we could just #define _GNU_SOURCE in gdm-session-record.c
for updwtmpx.
Bug: https://bugzilla.kernel.org/show_bug.cgi?id=216168

Subject: [PATCH 2/2] manager: Fix btmp record accounting
Before a user logs in they don't have a display.
btmp records currently need a display though, and they
get written when the user can't log in.
Furthermore, the display from X11 point of view is
somewhat archaic. We use wayland by default now.
In lieu of a display, this commit gives the btmp record
the seat id instead.
