2014-03-12backlight: Avoid restoring brightness to an unreadably dim levelJosh Triplett
Some systems turn the backlight all the way off at the lowest levels. Clamp saved brightness to at least 1 or 5% of max_brightness. This avoids preserving an unreadably dim screen, which would otherwise force the user to disable state restoration.
2014-03-12backlight: Fix copy/paste error printing an unrelated error codeJosh Triplett
udev_device_get_sysattr_value returns NULL on failure, but doesn't provide an error code; thus, when printing an error from it, don't print an unrelated error code from a previous call.
2014-02-19make gcc shut upLennart Poettering
If -flto is used then gcc will generate a lot more warnings than before, among them a number of use-without-initialization warnings. Most of them without are false positives, but let's make them go away, because it doesn't really matter.

2013-11-06util: unify reading of /proc/cmdlineLennart Poettering
Instead of individually checking for containers in each user do this once in a new call proc_cmdline() that read the file only if we are not in a container.
2013-10-19kerne-command-line: introduce option 'systemd.restore_state'Tom Gundersen
When set to 0 this will stop tools like the backlight and rfkill tools to restore state from previous boot. This is useful in case the stored state is bogus to the extent that it is preventing you from resetting it (e.g., the backlight settings cause the screen to be off on boot on a system where the backlight can not be adjusted directly from the keyboard).
2013-10-14backlight: include ID_PATH in file names for backlight settingsLennart Poettering
Much like for rfkill devices we should provide some stability regarding enumeration order, hence include the stable bits of the device path in the file name we store settings under.
2013-10-14backlight: always prefer "firmware"/"platform" backlights over "raw" ↵Lennart Poettering
backlights if we have both for the same device

2013-10-11Add support for saving/restoring keyboard backlightsBastien Nocera
Piggy-backing on the display backlight code, this saves and restores keyboard backlights on supported devices. The detection code matches that of UPower: http://cgit.freedesktop.org/upower/tree/src/up-kbd-backlight.c#n173 https://bugs.freedesktop.org/show_bug.cgi?id=70367 [tomegun: also work for devices named "{smc,samsung,asus}::kbd_backlight"]
2013-09-17backlight,random-seed: move state files into /var/lib/systemdLennart Poettering
Let's not scatter (private) files in /var around, let's place them all in /var/lib/systemd and below.
2013-08-14backlight: instead of syspath use sysname for identifying backlight devicesLennart Poettering
This makes the description string of the backlight service a bit nicer.
2013-08-14backlight: add minimal tool to save/restore screen brightness across rebootsLennart Poettering
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.
