Catalin, could you please test the latest upstream kernel available from
the very top line at the top of the page (the release names are
irrelevant for testing, and please do not test the daily folder)
following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow
additional upstream developers to examine the issue.
If the test did not allow you to test to the issue (ex. you couldn't boot into
the OS) please make a comment in your report about this, and continue to test
the next most recent kernel version until you can test to 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 by clicking on the yellow circle with a black pencil
icon, next to the word Tags, located at the bottom of the report description:
kernel-fixed-upstream
kernel-fixed-upstream-3.XY-rcZ
Where XY and Z are numbers corresponding to the kernel version.
If the mainline kernel does not fix this bug, please add the following tags:
kernel-bug-exists-upstream
kernel-bug-exists-upstream-3.XY-rcZ
Once testing of the upstream kernel is complete, please mark this bug's
Status as Confirmed. Please let us know your results.
Thank you for your understanding.

Title:
[ASUS-A7K laptop] screen brightness dimmed after kernel update
Status in xserver-xorg-driver-radeonhd:
Confirmed
Status in linux package in Ubuntu:
Incomplete
Bug description:
Hello,
Following the update from kernel version 3.13.0-34 to 3.13.0-35-generic the
screen brightness got a lot dimmer.
The Fn+F5/F6 control keys still work, in that the display gets dimmer and
brighter, but the maximum brightness is too low.
When starting ubuntu using the previous kernel release the display brightness
is alright.
I've looked around the web for ways to change the display brightness and I
checked that both files "/sys/class/backlight/acpi_video0/brightness" and
"/sys/class/backlight/radeon_bl0/brightness" have the maximum values, 15 and
255 respectively.
The release I am running is : Ubuntu 14.04.1 LTS
The XORG package version is : 1:7.7+1ubuntu8
Please feel free to contact me for any further information.
