When I press the appropriate keys on keyboard (Fn+up/Fn+down) the

Problem is I have not intel_backlight on /sys/class/backlight folder
but just acpi_video0 or dell_backlight (if I set acpi_backlight=vendor
on grub). Since I don't have intel_backlight folder I can't apply many
of the workaround found here and there.

Now I'm using xrandr to change the brightness:
xrandr --output LVDS1 --brightness 0.5
but since xrandr is a software overlay my battery life is horrible,
I'm stuck on 100% brightness. Beside this, sometimes the brightness
slider appears spontaneously without pressing any keys but again with
no effect.

[Kernel-packages] [Bug 1281176] Re: 8086:2a02 [Dell Vostro 1310] no brightness control on (x)ubuntu 13.10 / 14.04
Christopher,
I reinstalled my Windows Vista from my restoration DVD just to check if
brightness works and I had many difficult installing it.
I was able to install an old XP and I discovered multiple errors about ACPI and
the brightness control has issues on this OS too: I can see the brightness
slider moving but the luminosity don't change. I need a reflow or a moterboard
replacement.
Seems Linux is enumerating periferals in a different way and is less sensible
to hardware failures.
Please, mark this bug as invalid and close it. I'll contact you again
if, after the hardware fix, the issue is still present.

Today I've updated my 14.04 install and the osd no longer works.
Anyway the issue is present on the latest rc4 too.
Acpi_listen is reporting the keypressed code and the backlight files are
correctly updated but nothing changes.

[Kernel-packages] [Bug 1281176] Re: 8086:2a02 [Dell Vostro 1310] no brightness control on (x)ubuntu 13.10
** Description changed:
- When I press the appropriate keys on keyboard (which ones specifically?)
- the slider appears on the upper right corner of the screen but the
- brightness doesn't change.
+ When I press the appropriate keys on keyboard (Fn+up/Fn+down) the slider
+ appears on the upper right corner of the screen but the brightness
+ doesn't change.
Problem is I have not intel_backlight on /sys/class/backlight folder but
just acpi_video0 or dell_backlight (if I set acpi_backlight=vendor on
grub). Since I don't have intel_backlight folder I can't apply many of
the workaround found here and there.
WORKAROUND: /sys/class/backlight$ for i in /sys/class/backlight/*; do
echo -e \n $i; cat $i/{brightness,max_brightness,actual_brightness};

acpi_listen works just on new mainline kernel 3.13.2 (tried bot generic and
lowlatency) on stock kernel there isn't output at all:

Now I'm using xrandr to change the brightness:
xrandr --output LVDS1 --brightness 0.5
but since xrandr is a software overlay my battery life is horrible, I'm
stuck on 100% brightness. Beside this, sometimes the brightness slider
appears spontaneously without pressing any keys but again with no
effect.

[Kernel-packages] [Bug 1281176] Re: 8086:2a02 [Dell Vostro 1310] no brightness control on (x)ubuntu 13.10
Christoper,
I've tested the latest available Ubuntu 14.04 64bit iso from
http://cdimage.ubuntu.com/daily-live/current/ .
Same issues with both stock 3.13.0-8-generic and 3.14.0-031400rc2-generic (rc3
has not 64bit packages to test) from
http://kernel.ubuntu.com/~kernel-ppa/mainline/?C=N;O=D .
Tested both kernel with and without grub command line options. As soon
as the packages for kernel 3.14rc3 will be ready I'll test them.
Again, I can update from terminal and from funcion keys the
/sys/clsss/backlight files but with no effect on system.
Tags updated.

Federico Leoni, the issue you are reporting is an upstream one. Could
you please report this problem through the appropriate channel by
following the instructions _verbatim_ at
https://wiki.ubuntu.com/Bugs/Upstream/kernel ?
Please provide a direct URL to your e-mail to the mailing list once you
have made it so that it may be tracked.
Thank you for your understanding.

[Kernel-packages] [Bug 1281176] Re: 8086:2a02 [Dell Vostro 1310] no brightness control on (x)ubuntu 13.10
Federico Leoni, could you please confirm this issue exists with the
latest development release of Ubuntu? ISO images are available from
http://cdimage.ubuntu.com/daily-live/current/ . If the issue remains,
please just make a comment to this.
If reproducible, could you also please test the latest upstream kernel
available (not the daily folder) following
https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional
upstream developers to examine the issue. Once you've tested the upstream
kernel, please comment on which kernel version specifically you tested. If this
bug is fixed in the mainline kernel, please add the following tags:
kernel-fixed-upstream
kernel-fixed-upstream-VERSION-NUMBER
where VERSION-NUMBER is the version number of the kernel you tested. For
example:
kernel-fixed-upstream-3.14-rc3
This can be done by clicking on the yellow circle with a black pencil icon next
to the word Tags located at the bottom of the bug description. As well, please
remove the tag:
needs-upstream-testing
If the mainline kernel does not fix this bug, please add the following tags:
kernel-bug-exists-upstream
kernel-bug-exists-upstream-VERSION-NUMBER
As well, please remove the tag:
needs-upstream-testing
Once testing of the upstream kernel is complete, please mark this bug's
Status as Confirmed. Please let us know your results. Thank you for your
understanding.
