[Bug 1054647] Re: Backlight is not adjustable on HP 655 laptop
Sasa Paporovic, as per

an update is available for your BIOS (F.26). If you update to this
following https://help.ubuntu.com/community/BiosUpdate , does it change
anything?
If not, 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
Please note your current BIOS is already in the Bug Description, so
posting this on the old BIOS would not be helpful.
For more on BIOS updates and linux, please see
https://help.ubuntu.com/community/ReportingBugs#Bug_reporting_etiquette
.
Thank you for your understanding.

Title:
Backlight is not adjustable on HP 655 laptop
Status in The Linux Kernel:
Won't Fix
Status in “linux” package in Ubuntu:
Incomplete
Bug description:
I could not adjust the backlite of my HP 655 laptop.
Original vendor website:
http://h10010.www1.hp.com/wwpc/us/en/sm/WF05a/321957-321957-64295-3740644-3955548-5225017.html?dnr=1
The gnome-brightness applet is startable and the keys for brightness
adjustment (F2 for less and F3 for more) are recognized by the system
and can set the Software values, but also there is no real effect.
A check of
/sys/class/backlight
shows a redirect to
acpi_video0
which contains different entries like files for brightness.
So it is a bug of the type: "Backlight control does not work, but
there are entries in /sys/class/backlight"
The laptop was originally delivered with a SUSE Linux Enterprise
desktop 11 on Service Pack 2, which has contained kernel 3.0.x. On
this kernel version the Backlight was working. Unfortunally the SLED
11 SP2 was a obvious adapted one by HP with poperitary Software
components. Following this the vanilla 3.0.x kernel may also not be
able to handle the backlight with success.
