Gnome 3.10 brightness control broken

Hello everyone.

Since upgrading to Gnome 3.10, my brightness button down doesn't work right anymore.
It shows the OSD, but instead of lowering the value, it just flickers the bar left and right and does nothing.
Brightness up is working as intended, using the slider in the top-right menu works normally as well.

I upgraded the kernel at the same time as Gnome, but seeing as the button gets recognised, I think this is a desktop environment issue.

My notebook is an Asus UX32VD if that helps in any way.

Thanks in advance for any answers.

Can you control the brightness from the command line? What's the output of the following command?

ls /sys/class/backlight

ls /sys/class/backlight

My problem is that I can not brightness down via Fn key. I'm still able to brightness up with Fn key (but not brightness down) and full controll the brightness via slider on Gnome Shell's top panel

$ ls /sys/class/backlight
acpi_video0  acpi_video1  intel_backlight

I have the same problem. Brightness up and all the other fn combinations works well. I checked with Fedora 20 and problem exist in Fedora too.

So, it could a Gnome upstream bug, not an arch bug.

It affects systems with /sys/class/backlight/acpi_video0/max_prightness less then 10
Looks like it is fixed in Gnome. Lets wait an update.

The problem has ocorred on my laptop. On my Sony Vaio SVE series the brightness keys don't work - the OSD doesn't even appear.

It affects systems with /sys/class/backlight/acpi_video0/max_prightness less then 10

The value on this file is 15 for me.

mutter 3.10.2-2
gnome-desktop 1:3.10.1-2
gnome-settings-daemon 3.10.2-2
