Public bug reported:

The display connected on my R9 290 through DisplayPort connection turns
black during boot and never comes back again.

According to the power led, it is up and does not turn into power saving
mode.

According to xorg.0.log and System Settings / Display  the display is
perfectly detected.

This display worked perfectly fine using the same DisplayPort cable,
running the same driver on my Radeon HD 6670.

Description:	Ubuntu 15.04
Release:	15.04
