My GPUs are Intel hd4000 + Amd mobility radeon 7750M: /sbin/lspci | grep VGA 00:02.0 VGA compatible controller: Intel Corporation 3rd Gen Core processor Graphics Controller (rev 09) 01:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Chelsea LP [Radeon HD 7730M] (rev ff) If I don't set anything during the boot my dGPU is powered down successfully: cat /sys/kernel/debug/vgaswitcheroo/switch 0:IGD:+:Pwr:0000:00:02.0 1:DIS: :DynOff:0000:01:00.0 But in the meantime: xrandr --listproviders Providers: number : 1 Provider 0: id: 0x4a cap: 0xb, Source Output, Sink Output, Sink Offload crtcs: 4 outputs: 7 associated providers: 0 name:Intel So I cannot access my discrete GPU. If after the boot I use xrandr --setprovideroffloadsink radeon Intel then dGPU never switches off. Truly speaking runpm never worked for me even with Alex's early patches. -- You are receiving this mail because: You are watching the assignee of the bug. _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx http://lists.freedesktop.org/mailman/listinfo/dri-devel
