[Bug 1221790] Re: Screen brightness is maximum upon fresh boot

 

Given the number of bugs that the Kernel Team receives during any
development cycle it is impossible for us to review them all. Therefore,
we occasionally resort to using automated bots to request further
testing. This is such a request.

We are approaching release and would like to confirm if this bug is
still present. Please test again with the latest development kernel and
indicate in the bug if this issue still exists or not.

You can update to the latest development kernel by simply running the
following commands in a terminal window:

    sudo apt-get update
    sudo apt-get dist-upgrade

If the bug still exists, change the bug status from Incomplete to
Confirmed. If the bug no longer exists, change the bug status from
Incomplete to Fix Released.

Thank you for your help, we really do appreciate it.


** Changed in: linux (Ubuntu)
       Status: Confirmed => Incomplete

** Tags added: kernel-request-3.11.0-7.14
