Adjust the description of man page Xserver.1: technically both Xorg and
Xwayland are in the category of "X server". The reason we don't install
it here is not "it's not a part of this package", but we don't want to
overwrite a man page from another package.
Remove the creation of /etc/X11/xorg.conf.d: "Xorg" is "another X
server" so technically Xwayland (and other packages except Xorg and the
Xorg drivers) should have nothing to do with it. In my last build
/etc/X11/xorg.conf.d is empty.
With the default (-Dxvfb=true), Xvfb is built but not installed. So
leave the default (as Xvfb may be used in test), and add instruction to
install it if the user won't use xorg-server.
- create the /tmp/.X11-unix directory with permission 1777 using
/etc/sysconfig/createfiles
- add pam_loginuid.so as required in /etc/pam.d/gdm-launch-environment
- ensure /etc/X11/xorg.conf.d exists after installing xwayland (both
sysv and systemd)
