Dear all,
I've got an Intel NUC10i3FNH on which I've done a fresh install of
buster and then upgraded to bullseye. After exactly five minutes of
inactivity, the display (connected via HDMI) fades to black and then
shortly thereafter shuts off completely. How can I inhibit this
behaviour? I need the monitor to remain on all the time.
Here are some things I've tried so far:
1) Disable idle activation for my user account:
$ gsettings set org.gnome.desktop.screensaver idle-activation-enabled false
2) Disable sleep for my user account:
$ gsettings set org.gnome.settings-daemon.plugins.power
sleep-inactive-ac-type 'nothing'
$ gsettings set org.gnome.settings-daemon.plugins.power
sleep-inactive-ac-timeout 0
3) Disable sleep for the login manager:
# cat << EOF > /etc/gdm3/greeter.dconf-defaults
sleep-inactive-ac-timeout
sleep-inactive-ac-type='nothing'
EOF
4) Disable sleep for the X server globally:
# cat << EOF > /etc/X11/xorg.conf.d/xorg.conf.d
Section "ServerFlags"
Option "BlankTime" "0"
Option "StandbyTime" "0"
Option "SuspendTime" "0"
Option "OffTime" "0"
EndSection
EOF
5) Disable sleep for the current X session:
$ xset s off s noblank s 0 0 s noexpose
None of these measures have stopped the screen from blanking and
eventually shutting off altogether after five minutes. What else should
I be doing?
When I run xset q, the relevant output is as follows:
Screen Saver:
prefer blanking: no allow exposures: yes
timeout: 0 cycle: 0
DPMS (Energy Star):
Server does not have the DPMS Extension
Regards,
Tristan
