logind send the resume event for input devices and drm device, in any order. if we call vt_enter before logind resume the drm device, it leads to a driver error, because logind has not done the DRM_IOCTL_SET_MASTER on it. Keep the old workaround to make sure we call systemd_logind_vtenter at least once if there are no platform device Signed-off-by: Jocelyn Falempe <jfalempe@redhat.com> Reviewed-by: Hans de Goede <hdegoede@redhat.com>
X Server
The X server accepts requests from client applications to create windows, which are (normally rectangular) "virtual screens" that the client program can draw into.
Windows are then composed on the actual screen by the X server (or by a separate composite manager) as directed by the window manager, which usually communicates with the user via graphical controls such as buttons and draggable titlebars and borders.
