By default, GNOME enables a power profile designed for mobile devices
with battery usage. While useful for mobile devices, this setting should be disabled
for all other systems. To configure the system to disable the power setting, add or set
active to false in
/etc/dconf/db/local.d/00-security-settings. For example:
[org/gnome/settings-daemon/plugins/power]
active=false
Once the settings have been added, add a lock to
/etc/dconf/db/local.d/locks/00-security-settings-lock to prevent user modification.
For example:
/org/gnome/settings-daemon/plugins/power
After the settings have been set, run dconf update.
