[Bug 1312318] Re: brightness level not remembered on HP ZBook 15

 

Martin Konopka, thank you for reporting this and helping make Ubuntu
better. As per
http://h20564.www2.hp.com/hpsc/swd/public/readIndex?sp4ts.oid=5428369&swLangOid=8&swEnvOid=4192
an update to your computer's buggy and outdated BIOS is available
(1.33). If you update to this following
https://help.ubuntu.com/community/BIOSUpdate does it change anything?

If it doesn't, could you please both specify what happened, and provide the output of the following terminal command:
sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date

For more on BIOS updates and linux, please see
https://help.ubuntu.com/community/ReportingBugs#Bug_reporting_etiquette
.

Please note your current BIOS is already in the Bug Description, so
posting this on the old BIOS would not be helpful. As well, you don't
have to create a new bug report.

Once the BIOS is updated, if the problem is still reproducible, and the
information above is provided, then please mark this report Status New.
Otherwise, please mark this as Invalid.

Thank you for your understanding.

Title:
  brightness level not remembered on HP ZBook 15

Status in xserver-xorg-video-intel package in Ubuntu:
  Incomplete

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.
