I have similar trouble with vgaswitcheroo. 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.
