[Bug 1516213] Re: Lowering the brightness turns the monitor black in ubuntu 14.04

 

Roopa, please don't mark yourself affected unless you are going to be
releasing code that fixes this issue imminently (next 24-48 hours).

Despite this, you performed an apport-collect against a virtual machine,
which is not designed to have the brightness lowered.

Hence, you would need to run this on a physical host (not virtual
machine), or mark this report at Invalid.

** Changed in: xorg (Ubuntu)
