[nicola dmt <1570802@xxxxxxxxxxxxxxxxxx>]

It happened on a fresh install, and the computer is brand new so I don't
have any clue about the past!

I've tested upstream kernel, and the bug seems to be fixed, but please
check that I'm right:

- I turn on Ubuntu, I run glxgear, I get a normal frame rate of 60fps (I
guess I'm using Intel graphics)

- xrandr --listproviders gives:
Providers: number : 2
Provider 0: id: 0x66 cap: 0x9, Source Output, Sink Offload crtcs: 4 outputs: 3 associated providers: 0 name:Intel
Provider 1: id: 0x3f cap: 0x0 crtcs: 0 outputs: 0 associated providers: 0 name:HAINAN @ pci:0000:01:00.0

Note that there were only 2 listed when I reported the bug

- DRI_PRIME=1 glxgears now works, gives extremely high frame rate
(6000), renders smoothly

- xrandr --setprovideroffloadsink 0x3f 0x66 doesn't work anymore, now gives error: 
 X Error of failed request:  BadValue (integer parameter out of range for operation)
  Major opcode of failed request:  140 (RANDR)
  Minor opcode of failed request:  34 (RRSetProviderOffloadSink)
  Value in failed request:  0x3f
  Serial number of failed request:  16
  Current serial number in output stream:  17

So, even if I don't understand exactly how to switch rendering engine
systemwide, I think that using DRI_PRIME=1 actually turns the GPU on and
it is working fine now!

I'm tagging accordingly, but please tell me if I understand correctly.

Title:
  ATI Radeon not working: from no rendering to system freeze

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  Release: Ubuntu 16.04 LTS (pre-release daily build)

  Hardware: Dell Inspiron 15 5000 Series (Intel(R)) - 5559, hybrid
  graphics: Intel integrated + AMD Radeon(TM) R5 M335 4GB DDR3 GPU.

  I can't get the GPU to work properly. Examples: glxgears not showing
  output or crashing, blender causing the system to freeze.

  What I've tried:

  1] with the default configuration (integrated Intel card activated by
  default), glxgears works fine.

  2] DRI_PRIME=1 glxgears: THe windows gets drawn, but no content is
  rendered

  3] 
  Output from xrandr --listproviders:
     Providers: number : 3
     Provider 0: id: 0x66 cap: 0x9, Source Output, Sink Offload crtcs: 4 outputs: 3 associated providers: 2 name:Intel
     Provider 1: id: 0x3f cap: 0x6, Sink Output, Source Offload crtcs: 0 outputs: 0 associated providers: 2 name:HAINAN @ pci:0000:01:00.0
     Provider 2: id: 0x3f cap: 0x6, Sink Output, Source Offload crtcs: 0 outputs: 0 associated providers: 2 name:HAINAN @ pci:0000:01:00.0

  So I change with:
  xrandr --setprovideroffloadsink 0x3f 0x66

  4] DRI_PRIME=1 glxgears now gives:
