From 3731acf1acfb4a6eb68374a5b137f3b368f63381 Mon Sep 17 00:00:00 2001 From: Lennart Poettering Date: Wed, 14 Aug 2013 01:57:02 +0200 Subject: backlight: add minimal tool to save/restore screen brightness across reboots As many laptops don't save/restore screen brightness across reboots, let's do this in systemd with a minimal tool, that restores the brightness as early as possible, and saves it as late as possible. This will cover consoles and graphical logins, but graphical desktops should do their own per-user stuff probably. This only touches firmware brightness controls for now. --- units/systemd-backlight@.service.in | 21 +++++++++++++++++++++ 1 file changed, 21 insertions(+) create mode 100644 units/systemd-backlight@.service.in (limited to 'units/systemd-backlight@.service.in') diff --git a/units/systemd-backlight@.service.in b/units/systemd-backlight@.service.in new file mode 100644 index 0000000000..14b12198e8 --- /dev/null +++ b/units/systemd-backlight@.service.in @@ -0,0 +1,21 @@ +# This file is part of systemd. +# +# systemd is free software; you can redistribute it and/or modify it +# under the terms of the GNU Lesser General Public License as published by +# the Free Software Foundation; either version 2.1 of the License, or +# (at your option) any later version. + +[Unit] +Description=Load/Save Screen Backlight Brightness of %f +Documentation=man:systemd-backlight@.service(8) +DefaultDependencies=no +RequiresMountsFor=/var/lib/backlight +Conflicts=shutdown.target +After=systemd-readahead-collect.service systemd-readahead-replay.service systemd-remount-fs.service +Before=sysinit.target shutdown.target + +[Service] +Type=oneshot +RemainAfterExit=yes +ExecStart=@rootlibexecdir@/systemd-backlight load %f +ExecStop=@rootlibexecdir@/systemd-backlight save %f -- cgit v1.2.3-54-g00ecf
