On my Fujitsu Lifebook A512 I should be able to adjust the brightness
pressing Fn+F6 or Fn+F7. The brightness-indicator pop-up works but the
brightness doesn't change. This should be related to the cpi_video0 /

Hi Christopher,
in the last couple of days I tried the kernels I didn't try before and now I
can tell for sure that the fix arrived with the v3.16rc1 kernel. I also had a
look at the bisect documentation and tried to move my first steps.
In the meantime Aaron Lu, the guy that was looking after
Before performing the reverse bisect process I thought to ask directly
in the linux-acpi mailing list which was the patch (or the set of
patches) that have fixed the acpi/backlight issue .

At this stage a backport would make sense only to Ubuntu 12.04 LTS which is
going to be supported till 2017. I don't use it but of course a backport could
be useful for other people who are using the 12.04 and planned to use it til
the EOL.
I think it's up to the developers to take a decision.
Hi,

are infinite ways to reach the download links of the 17.10.
