Status in xorg-server package in Ubuntu: Won't Fix Bug description: 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.
