Comment 147 for bug 1554613

I'm having this same issue on a Dell 7537 running Ubuntu 16.10 (kernel 4.8).

The flickering that occurs is a rapid change in the brightness of the screen, in a random, persistently manner (it never stops).
Not so often the screen goes all white and quickly returns to normal.

It's interesting to mention that on Ubuntu 16.04 (kernel 4.4) the bug appears to be fixed, as the flickering does not occur.
