Jani, all,
On a Lenovo X1 Carbon if the display is off when suspend is entered
it will be off when it is resumed. A key must be pressed to restore
normal brightness.
xset dpms force off

(screen off, press any key)

With this setup, something has happened: in xorg, when screen goes to
screensaver and after, enters into Standby mode, when I press a key,
