gdm-48.0-160000.3.1

- Add gdm-service-keytable.patch: set KEYMAP to XkbLayout for GNOME
  when using gdm-systemd instead of xdm (bsc#1248831, bsc#1250366).

- Create /run/gdm in case it would not exist yet; this could
  potentially happen on offline upgrades.

- Move migration marker from /var/tmp to /run/gdm (boo#1249017).

- Fix syntax error in gdm's %pre script.

- Add gdm-plymouth-quit-wait.patch: Disable plymouth-quit-wait.service
  (bsc#1243439).

- Ensure migration to gdm.service also happens during upgrade when
  gdm is installed first and we thus lose the updte-alternative
  link which would be part of tgdm-xdm-integration (boo#1247418).

- gdm-fingerprint.pamd: Fix inclusion of common-account instead
  of postlogin-account

- pam.d: removes pam_env from auth stack for security reason
  [bsc#1243226, CVE-2025-6018]

- Add gdm-fix-wrong-path-gdm-config.patch: Add missing slash when
  gdm-config building dconf database path (bsc#1232669).

- Add -Ddistro=generic to make gdm-config work (bsc#1232669).

- Drop obsolete gnome-common BuildRequires. Add itstool
  BuildRequires.

- SLES16 won't ship pulseaudio-gdm-hooks so remove the last missing
  bits.

- Disable X11 support on SLE:
  * SLFO will only support Wayland
  * This is required to avoid a fallback to X11 sessions which
    makes GDM crash
  * With this change gdm-exclude-61-gdm-rules-file.patch is
    not needed anymore

- No longer rm -vrf
  %{buildroot}%{_datadir}/polkit-1/rules.d/20-gdm.rules, now that
  boo#1239719 is resolved.
