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.
