From 1692d4a91d95fecd5642b0c92bc2c5b0dbcb4184 Mon Sep 17 00:00:00 2001 From: Neal Gompa Date: Fri, 29 Oct 2021 09:37:33 -0400 Subject: [PATCH] classic: Install the session for Wayland and ship override sessions The regular GNOME session ships with three options: * GNOME * GNOME on Wayland (available when GDM starts in X11) * GNOME on Xorg (available when GDM starts in Wayland) The main GNOME session is set up so it works to match how GDM starts, so GNOME is on Wayland if GDM is (or GNOME is on X11 if GDM is). For GNOME Classic, we are missing this setup, so port this behavior over from the GNOME session setup.
