Public bug reported:

Yesterday I decided to learn how to switch between my low power usage
GPU and my discrete GPU in my laptop using Prime. I started by running
this command: xrandr --listproviders.

I got the following result:

    Providers: number : 2 Provider 0: id: 0x75 cap: 0x9, Source Output,
Sink Offload crtcs: 3 outputs: 3 associated providers: 1 name:AMD Radeon
R6 Graphics @ pci:0000:00:01.0 Provider 1: id: 0x3f cap: 0x4, Source
Offload crtcs: 0 outputs: 0 associated providers: 1 name:AMD Radeon (TM)
R7 M360 @ pci:0000:03:00.0

I then ran this command to switch to my discrete GPU: xrandr
--setprovideroffloadsink 1 0.

This resulted in the following result to my GPU with this command:
DRI_PRIME=1 glxinfo | grep "OpenGL renderer"

    OpenGL renderer string: AMD Radeon (TM) R7 M360 (AMD ICELAND / DRM
3.18.0 / 4.13.8-041308-generic, LLVM 5.0.0)

Now however when i attempt to switch back to using my low powered Radeon
R6 with this command I get: xrandr --setprovideroffloadsink 0 1

    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: 0x75 Serial number of failed request: 16 Current serial number
in output stream: 17

I should mention I am logging into the Gnome session using Xorg on
Ubuntu 17.10. I would love to be able to switch back to my R6 so any
help is much appreciated.
