[Bug 1261853] Re: 8086:0166 [Dell Inspiron 15R 5521] Impossible to adjust the screen backlight
A customer of mine gave me his old notebook because he bought a new one.
The laptop is running an p to date Xubuntu 13.10 64bit. Now I'm
suffering similar issue with brightness control: when I press the
appropriate keys on keyboard the slide appears on the upper right corner
of the screen but even if it changes the setting has no effect on the
system . The notebook I have has an Intel X3100 integrated video
00:02.0 VGA compatible controller: Intel Corporation Mobile GM965/GL960
Integrated Graphics Controller (primary) (rev 0c)
I tried different combinations on grub but no one resolved the issue.
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).
--
effe@Vostro1310:/sys/class/backlight$ for i in /sys/class/backlight/*; do echo
-e \n $i; cat $i/{brightness,max_brightness,actual_brightness}; done
/sys/class/backlight/dell_backlight
1
7
1
--
If I increase the backlight the files are correctly updated:
--
/sys/class/backlight/dell_backlight
7
7
7
--
acpi_listen works just on new mainline kernel 3.13.2 (tried bot generic and
lowlatency) on stock kernel there isn't output at all:
video/brightnessup BRTUP 0086 K
video/brightnessup BRTUP 0086 K
video/brightnessup BRTUP 0086 K
video/brightnessdown BRTDN 0087 K
video/brightnessdown BRTDN 0087 K
video/brightnessdown BRTDN 0087 K
Now I'm using xrandr to change the brightness:
effe@Vostro1310:/sys/class/backlight$ xrandr --output LVDS1 --brightness
0.5
What can I try to triage the issue?
Thanks.

[Bug 1261853] Re: 8086:0166 [Dell Inspiron 15R 5521] Impossible to adjust the screen backlight
Alex Barattini, thank you for updating your BIOS. Could you please test the latest upstream kernel available (v3.13-rc3, as rc4 doesn't have all the files yet) 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-v3.13-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.
