[Bug 1499491] Re: Display connected on DisplayPort turns black during boot and never returns

 

I plugged my graphics card into an old computer I have (Asus M2NPV-VM).
The other computer was running Ubuntu 14.04.3 with Linux version 3.13.0-63-generic (dmesg log attached).

The same display connected on the same displayport did work fine.
However, it was slow because the GPU was not yet well supported in Linux version 3.13.

I believe My displayport problem might be BIOS related.
I think I will have to wait for a BIOS update to use my displayport again.
Until then I will use DVI ports.

Title:
  Display connected on DisplayPort turns black during boot and never
  returns

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  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.
