Script for measure idle time and disable keyboard backlight / display brightness automatically

[ldrahnik]

, probably only on battery mode because on AC it might be annoying? What about implementing generally not only for Asus laptops to https://github.com/ldrahnik/power-supply-mode-switcher-driver? Does not provide TLP something like this already? Used power management tool by Elementary OS after half a minute disable keyboard backlight to lowest level 1 and decrease a little even brightness of display - https://gitlab.freedesktop.org/upower/power-profiles-daemon exactly what I want but it looks like it is not configurable). To Asus laptops is only related file where is changed brightness (asus-nb-wmi) module ls /sys/devices/platform/asus-nb-wmi/leds/asus::kbd_backlight/power.

Found gnome-gsettings:

• /org/gnome/settings-daemon/plugins/power/idle-brightness - The brightness of the screen when idle (works even on backlight of keyboard, it works because of upower? TODO: try to disable)
• /org/gnome/desktop/screensaver/idle-activation-enabled - Set this to TRUE to activate the screensaver when the session is idle.
  DEPRECATED: This key is deprecated and ignored. Set org.gnome.desktop.session idle-delay to 0 if you do not want to activate the screensaver.

Solved on Gnome (Elementary OS) by setting up /org/gnome/settings-daemon/plugins/power/idle-brightness to 10 which decreases to almost minimum brightness display and disables keyboard backlight too (because is used round of value?), on touch is then automatically set up previous value of brightness and display. NumberPad backlight is not disabled, the driver has its own configurable value to do this.

// EDIT: related probably to Elementary OS directly or used upower because it disable brightness to mentioned dconf value after 30 seconds

// EDIT: idea add this to NumberPad driver, udev rule (optionally? probably) Check change to battery mode? Test it works even during the start!! Then take this value /org/gnome/settings-daemon/plugins/power/idle-brightness and after 30s - configurable in config value decrease the brightness to level to percental ekvivalent, so value 10 will means brightness is disabled entirely, because first level is higher than this 100/8=12.5 so it will send 0x00. Should be disabled this functionality using org.gnome.settings-daemon.plugins.power

// TODO: more research on how is it done on Elementary OS. But do I need to know that to implement this idea?

// TODO: jak je udelane to, že se jas zlumí a potom se opět obnoví, kde je to uložené ta informace? Zkusit projít udev rules? Které jsou vykonané v tu chvíli? Jestli to není v něm? Díval jsem se na sudo gedit 99-systemd.rules. Možná by driver měl mít takové udev rule, aby se jas zlumil při překlopení víka např? Jiná situace mě nenapadá.

// EDIT: https://help.gnome.org/admin//system-admin-guide/3.12/power-dim-screen.html.en - idle delay is related to screensaver from gnome. Looks like screensaver disables the display entirely and ignore idle-brightness (tried 50%). Would be better I gues implement this by own ignoring any gnome settings?
