It both works and doesn't work for me.

The kernel module is fine, the X Server loads and seems to open the device correctly, but the screens stay blank, then turn off.
The attached tar file has dmesg output and the Xorg and gpu-manager log files. The only thing I can see is the gpu-manager log complains that /dev/dri is absent.

I can force the screens to stay on ( but still blank ) by running
amdconfig --initilal. The main change then is that ukiOpenDevice returns
9 rather than 11 ( can't find any documentation for this function -
assume it is proprietary ).

To add more strangeness, if I boot into recovery mode, and run 'startx'
as the root user, I get an empty X desktop on display :1 that appears to
be the Unity desktop without any menus/launchers, and no window manager.
But I can run an X terminal and run gedit, eclipse, and firefox, from
which I am writing this comment. However, the VTs that should be
provided by fglrx do not work.

This is with a new 15.10 installation ( keeping personal files ), not an
upgrade, using an R9 290. It clearly works as an X server, but
configuration or permissions in the installation must be askew.

Title:
  FGLRX incompatible with gcc 5

Status in Release Notes for Ubuntu:
  Fix Released
Status in fglrx-installer package in Ubuntu:
  Fix Released
Status in fglrx-installer source package in Wily:
  Fix Committed

Bug description:
  SRU Request:

  [Impact]

  The fglrx driver is not compatible with gcc 5.x. This causes the
  kernel module to crash on initialisation. As a result, users will boot
  into a black screen, as X will fail (except on Intel+AMD hybrid
  systems, where intel is used).

  [Test Case]
  1. Either install (or upgrade to) Ubuntu 15.10 and fglrx
  2. Reboot
  3. Check the display, and the output of the "dmesg | grep fglrx" command (to see the actual crash)

  Expected results: the system should be able to start X correctly.

  Actual results:
  The kernel module fails and X doesn't start.

  [Regression Potential]
  Low. Forcing fglrx to use gcc 4.9 is only a temporary workaround, and will be replaced with the proper fix once AMD makes it available.


  __________________________________________________________________________

  With a R9 280 and FGLRX on ubuntu 15.10 the graphics lock up. I am
  able to SSH into the machine. I booted the older kernel
  (4.1.0-3-generic) and it works with FGLRX. After purging FGLRX and
  using xserver-xorg-video-radeon I am able to get the graphics working,
  but even it has issues with my display port (The DVI ports are working
  correctly).
