I'm running Gnome (Wayland) on Arch Linux. I have configured the environment not to go to suspend, etc. when the lid is closed. When I close the lid, the monitor turns off for a second or two (as though it's responding to the laptop lid state changing), then turns back on. Likewise, when I open the lid, it turns off for a second or two, then turns back on. (If I wasn't careful, I might have thought the monitor was turning off when closing the lid...sneaky Gnome!)

How do I make it so that the computer stays on and responds to, e.g. network events, but the monitor doesn't stay on all day?

  • I don't use Gnome, but is something like xset dpms force off acceptable? – Sparhawk May 27 '18 at 6:31
  • Wayland? One of the commands here might work. – Sparhawk May 28 '18 at 12:53
  • From freedesktop: If your session manager handles ... the laptop lid switch on its own it is welcome to do so, but needs to disable logind's built-in handling of these events. So you might look for clues in the interaction of systemd-logind and gnome/wayland. – meuh May 28 '18 at 14:42
  • @Sparhawk Since I'm not running X, that doesn't work. – lmat - Reinstate Monica May 29 '18 at 14:45
  • I'm not sure what happened to your comment, but was my link helpful? – Sparhawk May 29 '18 at 21:49

Use gdm. It handles this and many other things automatically.

    Could you elaborate on that a bit? Maybe tell us where to set the options needed? – Mio Rin May 31 '18 at 2:19
  • @Mioriin I didn't have to set up anything. sudo pacman -Syu gdm; sudo systemctl enable gdm; sudo reboot; That's it. That's why my answer has the word "automatically" :-) – lmat - Reinstate Monica Jun 1 '18 at 3:25
