restored at boot.

I have this already in my grub.cfg. Without this the Fn-keys for brightness
aren't working.

But this doesn't fix the problem with maximum brightness on boot (at
ThinkPad X230).

This has to do with ACPI.
I solved this problem on my Asus Zenbook UX31E (with latest BIOS) this way :
1) I addedacpi_osi='!Windows 2012' acpi_backlight=vendor in
/etc/default/default so that the line looks like
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi_osi='!Windows 2012'
acpi_backlig
Same problem here on a ThinkPad X230 running Ubuntu 13.04.
The brightness-setting isn't saved and goes to maximum on every reboot
(annoying!) .
As a workaround i put
echo 10 > /sys/class/backlight/acpi_video0/brightness
into /etc/rc.local
This worked until the latest kernel update. Now the br
This:
pkexec /usr/lib/gnome-settings-daemon/gsd-backlight-helper --set-brightness 0

Yes, the power plugin does not store the current brightness and restores
it on startup.

Generally these types of issues should be analyzed as gnome-power-
manager issues first, then driver issues if g-p-m can be ruled out.
