• GDM not powering down monitor when logged out.

    Hi all does anyone know how GDM is supposed to handle powering down the monitor when at the login screen. I disabled Lightdm and enbled GDM, then restarted, logged in under GNOME in X and set screen saver settings.

    Everything works perfectly, caffeine, screen blanking and not blanking when watching a video, however, when I log out the monitor just stays on forever.

    I searched all over but can’t find a solution. Is this a bug in Antergos I wonder. I installed with the latest 17.12 ISO.

  • i will try what i got here… but i think most Displays will went off also on its own…

  • I had the same hardware working fine under Manjaro with gnome 3.26, but I was running Antergos at work and wanted to change. Maybe I will try an older install ISO, There doesn’t seem to be anywhere to set this.

  • seems that gsettings set org.gnome.desktop.session idle-delay 0 for gdm so it will not power off the display…

    you can change this only under gdm user:

    you need to do this from TTY3 by pressing [Ctrl+Alt+F3] login as root and:

    su - gdm -s /bin/sh
    export $(dbus-launch)
    GSETTINGS_BACKEND=dconf gsettings set org.gnome.desktop.session idle-delay 30

    will put power off to 30 seconds…

  • OMG I can’t believe what the problem was here. I had changed the Secure Boot in the bios to “Other OS” From “Windows UEFI System”, once I changed it back GDM started working correctly. how sad is that. I’m looking you you ASUS.

    Thanks for all the help people.
