I have tested many distros - Arch, OpenSuSe 13.1, Fedora 20, ALT Linux p7, Sabayon, Mageia 4. Many of them are based on systemd. It does not matter what init system they use, but all of them have very usefull script (or binary program, I don't know) for saving and restoring backlight level on laptop. In these distros there is a script for save and restore backlight levels for two video-cards (acpi_video0 and acpi_video1). During system boot it is indicated as follows: " [ OK ] Started Load/Save Screen Backlight Brightness of acpi_video1. [ OK ] Started Load/Save Screen Backlight Brightness of acpi_video0. ". ========================================= Steps to reproduce: 1. User boots laptop (cold boot, not wake from suspend) 2. User sets comfortable backlight level 3. User ends his/her work by shutting down the laptop (not suspend, so backlight level is not saved) 4. Go to 1 (another cold boot with reseted backlight level). ========================================= According to the list of duplicates and bug heat this bug/feature request is very important. As you know laptop market share is gigantic (see for example http://www.statista.com/statistics/276772/ultrabook-share-of-global-notebook-market-since-2011/ for stats). Also Ubuntu and Debian market share are increasing. So I can't believe why this usability fault exists in Ubuntu (and Debian) for years. It seems that guys from `systemd` understand the problem correctly (sooner or later - on 14 Aug 2013, see https://github.com/systemd/systemd/commits/56f64d95763a799ba4475daf44d8e9f72a1bd474/src/backlight/backlight.c ), but `upstart` and `sysvinit` developers not. As you can remember I tried to fix the problem by myself (see my comment on askubuntu http://askubuntu.com/questions/151651/brightness-is-reset-to-maximum-on-every-restart/227553#227553) - I created first version of an init script for saving and restoring backlight level (on 10 Dec 2012 - two years ago). It had one disadvantage - it operates only when laptop has one graphical adaptor and its name was hardcoded to the script (*acpi_video0* in my case). So on 2014-12-28 I presented new version of a script - it can save and restore backlight levels of all graphical, adaptors, which are found in `/sys/class/backlight/*`. The init script with symlink aPlease note: ire packed to archive (see attachment to comment #18 - https://bugs.launchpad.net/ubuntu/+source/upstart/+bug/1270579/+attachment/4288756/+files/upstart_brightness.tar.gz ). The script is tested on Ubuntu Precise 12.04.5 and Ubuntu Trusty 14.04.1. If you have installed its previous version (from comment #15) - you can remove its files with commands: sudo rm /etc/rc?.d/?25backlight /etc/init.d/brightness then extract new version with commands: sudo tar -zxvf upstart_brightness.tar.gz -C / I hope my script will help somebody. Thanks for testing! To Ubuntu developers: please contact me if you are ready to include and distribute my script to 12.04 and 14.04 deb-pakages. ========================================= ProblemType: Bug DistroRelease: Ubuntu 14.04 Package: initscripts 2.88dsf-41ubuntu5 ProcVersionSignature: Ubuntu 3.13.0-4.19-generic 3.13.0-rc8 Uname: Linux 3.13.0-4-generic i686 ApportVersion: 2.13.1-0ubuntu1 Architecture: i386 CurrentDesktop: GNOME Date: Sun Jan 19 17:20:26 2014 InstallationDate: Installed on 2013-10-20 (91 days ago) InstallationMedia: Ubuntu 13.10 "Saucy Salamander" - Release i386 (20131016.1) SourcePackage: sysvinit UpgradeStatus: Upgraded to trusty on 2013-11-19 (61 days ago) To manage notifications about this bug go to: https://bugs.launchpad.net/elementaryos/+bug/1270579/+subscriptions -- Mailing list: https://launchpad.net/~touch-packages Post to : touch-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~touch-packages More help : https://help.launchpad.net/ListHelp
