Bug Description

Anytime I boot up the system, it always sets the display brightness to 100%.

I can reduce the brighness using the Fn F9 key stroke. Similarly I can increase the brighntess using the Fn F10 combination. (This did not work until recently - see my bug report 1257766). However, even now the chosen value is not remembered. After each start of the system I have to set a convenient brightness level.

I do have the latest version of BIOS installed. My computer is a dual-boot one so that it installs BIOS updates when it runs Windows 7. The problem with the brightness level persists. I am using ubuntu-MATE (see below for more details on the OS).

Output of the sudo dmidecode ... command is:

L70 Ver. 01.33
07/21/2015

Please note that in HP they have a little ambiguity in dates of the BIOS update: on their web page they show 29th July. To be sure that I really have the latest BIOS installed, I tried to download the package from the HP site and launched the binary (in Windows, just to see its description). It showed its date as 21st July.

The bug description is the same as the original one: Anytime I boot up the system, it always sets the display brightness to 100% which is too much. I can control the brightness level using Fn F9 and Fn F10 combinations of keys. Unfortunately, my setting is not remembered. On the contrary, in Windows 7 the brightness level that I choose remains remembered.

BTW, today I made a clean installation of the newest 64-bit ubuntu version: 15.10, with the MATE desktop. (I installed the newest daily build from the 3rd October.) The brightness issue is the same as it was in ubuntu-mate 15.04 and also in LinuxMint 17 which I was using for some period in the past.
