Hi Mario,
Thanks for your response, that's very useful for me as we're encountering
another backlight issue.
BTW, I'm closing this issue as it's been fix in 3.13 kernel.

Hi Kao,
I apologize but I have not installed *ubuntu anymore. But I can confirm,
that with the distribution I have currently running on this laptop, the
display goes off if I switch down to the lowest level with the fn-keys.
Currently running Kernel 3.13.5.
Hope this helps.

Hi Mario,
I'm just curious, with the 3.13 kernel, does the lowest brightness level turns
off the screen?

For your information. The bugs for the Acer Aspire V5-573g are fixed.
Brightness works correct, shutdown works and even suspend to ram is
functional now. Tested with mainline Ubuntu 3.13.(trusty) kernel through
Kubuntu 13.10. (https://wiki.ubuntu.com/Kernel/MainlineBuilds).

This "initial brightness zero bug" is an ACPI problem and a work around
fix patch is headed for kernel 3.13. Chances are good that it gets
backported to kernel 3.12. Details at:

bp0 / Mario Kleinsasser, the issue you are reporting is an upstream one.
Could one of you please report this problem through the appropriate
channel by following the instructions _verbatim_ at

Bisect done. For explanation:
good means: The laptop starts with display brightness on full power, but
low(er) resolution and the Fn+ keys are not working
bad means: The laptop starts with black display (0 brightness), Fn+ keys
are working and you can level up the brightness trough the Fn+ keys.
Ah, I'am sorry, I've greped for Ubuntu-xyz -> my fault, but that was my missing
link :) (and I only used --oneline)
Now I know how to search the diff log and how to find the commit I need. I'am
going to try bisect.Thanks!

>"...Ubuntu-3.7.0-7.15 commit istn't in the Raring git..."
This is incorrect. The Raring git would include mostly everything in the
Quantal git, plus the commits that make Raring, Raring:
http://kernel.ubuntu.com/git?p=ubuntu%2Fubuntu-raring.git&a=search&h=HEAD&st=grep&s=3.7.0
Oh, yes, yes, but the Ubuntu-3.7.0-7.15 commit istn't in the Raring git
and the Ubuntu-3.8.0-0.1 commit is not in the Quantal git. Thats my
problem or maybe I don't understand something. To bisect commits, I need
those commits inside one git, right?

Mario Kleinsasser, now that it is known 3.7.0-7.15 is the latest kernel
tested not to show the problem, and 3.8.0-0.1 is, the next step is to
commit bisect between these two kernel versions (not test different
kernel version but different commit versions) following

I've tried Kernel Raring Ringtail commit 1161744, 3.8.0-0.1. This kernel
