I'm using Arch Linux + GNOME3 on desktop, and when the system starts or the user logs out, gdm
displays the login screen for about 20 seconds and then turns off the display (although the computer is still running). Is it possible to disable this? I want the monitor to keep displaying the login screen "forever". I couldn't find any way to configure this.
That's because of the idle-delay
setting. To change it you'll have to alter the corresponding dconf
key (and do that as the gdm
user):
switch to a
VT
(e.g. Ctrl+Alt+F3), login as root and run:su - gdm -s /bin/sh
to switch user to
gdm
.then run:
export $(dbus-launch)
and set idle delay to
0
(which translates to never):GSETTINGS_BACKEND=dconf gsettings set org.gnome.desktop.session idle-delay 0
run
exit
or hit Ctrl+D to return to root account.reboot your machine or restart the display manager:
systemctl restart gdm
Just as an expansion to don_crissti's answer:
Step 2 didn't work for me. I am on Gnome/gdm 3.28 and I don't have org.gnome.desktop.session
, but this one worked for me:
GSETTINGS_BACKEND=dconf gsettings set org.gnome.settings-daemon.plugins.power sleep-inactive-ac-type 'nothing'
Adjusting the following via the dconf-editor
might help fine-tune the sleep related settings:
sleep-inactive-ac-timeout
sleep-inactive-ac-type
sleep-inactive-battery-timeout
sleep-inactive-battery-type
Worth a try, in my case it was the way to get the machine to stay awake during periods of inactivity.
