Red Hat Bugzilla – Bug 753415
I can't modify brightness with HP Elitebook 8560w
Last modified: 2013-07-31 22:08:23 EDT
Description of problem:
I have the HP Elitebook 8560w with a nVidia's graphical card :
01:00.0 VGA compatible controller: nVidia Corporation GF108 [Quadro 1000M] (rev a1)
But I can't modify the brightness, xbacklight or to modify /sys/class/backlight/acpi_video0/brightness.
The only solution : the command « xrandr --output LVDS-1 --brightness 1.0 » is functional. But it's not very easy…
And the touch in the keyboard for this is recognize by Gnome 3.2 (an pop-up with brightness image appears) but nothing, the brightness is the same !
I use the nouveau driver.
Thanks for reporting this -- since the problem is not specific to xbacklight, from similar experiences in the past (one of my laptop -- with an *Intel* integrated graphics controller, believe it or not -- had a similar problem) -- this is better handled by kernel developers.

Seems like the same issue is being discussed in freedesktop's bugzilla in Xorg/
Nouveau section: https://bugs.freedesktop.org/show_bug.cgi?id=47965
Is this still a problem with 3.8.2 in updates-testing?

This message is a reminder that Fedora 17 is nearing its end of life.
Approximately 4 (four) weeks from now Fedora will stop maintaining
and issuing updates for Fedora 17. It is Fedora's policy to close all
bug reports from releases that are no longer maintained. At that time
this bug will be closed as WONTFIX if it remains open with a Fedora
'version' of '17'.
Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version'
to a later Fedora version prior to Fedora 17's end of life.
Bug Reporter: Thank you for reporting this issue and we are sorry that
we may not be able to fix it before Fedora 17 is end of life. If you
would still like to see this bug fixed and are able to reproduce it
against a later version of Fedora, you are encouraged change the
'version' to a later Fedora version prior to Fedora 17's end of life.
Although we aim to fix as many bugs as possible during every release's
lifetime, sometimes those efforts are overtaken by events. Often a
more recent Fedora release includes newer upstream software that fixes
bugs or makes them obsolete.
Fedora 17 changed to end-of-life (EOL) status on 2013-07-30. Fedora 17 is
no longer maintained, which means that it will not receive any further
security or bug fix updates. As a result we are closing this bug.
If you can reproduce this bug against a currently maintained version of
Fedora please feel free to reopen this bug against that version.
Thank you for reporting this bug and we are sorry it could not be fixed.
