[Bug 954661] Re: backlight brightness not adjustable by default on Dell XPS 13
Hi. I have the exact same intel card id (8086:0116), but my Dell is the n411z. I am facing the same probelm with the latest ubuntu kernels i.e. my brightness function keys do not work with 13.10 and 14.04 (i.e. kernels 3.11 and 3.13). Whilst these keys worked perfectly till 13.04. More info can be found here: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1280394 Unfortunately even if I installed the latest permitted BIOS by DELL for my laptop (A06), there is no option for legacy rom that I can enable and see if that will fix the problem. I tried various boot parameters but none worked. The brightness function keys do not even produce any results in acpi_listen. Do you have any ideas how to fix it?

[Bug 954661] Re: backlight brightness not adjustable by default on Dell XPS 13
I spoke a bit too soon it seems. It had been working fine. Just now I left my laptop for ~5 minutes (it was on, screen open, brightness on full when I left). I came back and found the brightness stuck on minimum (and my session had timed out, prompting me for my password - presumably something that happened as part of the time out is what triggered this bug and thus the brightness to be stuck on minimum). Echoing 0 to /sys/class/backlight/intel_backlight/brightness did not fix it. Suspending and unsuspending the laptop did fix it - the brightness was back at full when I unsuspended, and I have control again. I seem to recall reading either further up on here or elsewhere that the root cause is/was a race condition. I know next to nothing about things at this level (my current expertise is in Android and at the SDK level) but what I saw just now seemed like it could be explained in terms of a race condition. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/954661 Title: backlight brightness not adjustable by default on Dell XPS 13 To manage notifications about this bug go to: https://bugs.launchpad.net/dell-sputnik/+bug/954661/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

To all those wondering about backlight in Precise and Quantal, if you switch your BIOS mode to UEFI, and reinstall Ubuntu in UEFI mode, it will fix the brightness issue. You can use your function keys out of the box, and they will change the brightness accordingly.

I can confirm this regression in 3.8.0-22. Only noticed it when I went
on battery today.
Fix for me was the same as beerfan above. I also went one step further
and added:
echo 0 /sys/class/backlight/intel_backlight/brightness
to rc.local and the following:
#!/bin/sh
# to fix backlight issues on resume

echo 0 /sys/class/backlight/intel_backlight/brightness

esac
to /etc/pm/sleep.d/99-backlightfix (remember to make it executable!).
Might need to alter it a bit to make it work for hibernate but
brightness control works on resume. Will test again on the next kernel
update.
