I use Lenovo Z51-70 laptop with Intel HD5500 and discrete Radeon R9 M375. I wasn't ever be able to switch to faster card and use it with radeon module. (I only was able to run it with fglrx proprietary driver, but it was running so ugly so computer wasn't usable at all).
Once I switched (that was kernel 4.4 i guess), but my screen was blank and after that and I could only reboot laptop to see anything (reboot reaction normally, CTRL+ALT+DEL) But content of vgaswitcheroo changed from: 0:IGD:+:Pwr:0000:00:02.0 1:DIS: :DynOff:0000:04:00.0 to: 0:IGD: :Off:0000:00:02.0 1:DIS:+:DynOff:0000:04:00.0
So THERE'S HOPE i thought :D
From kernel 4.5 I have such error and /sys/kernel/debug/vgaswitcheroo file no
longer exists.
If I could provide some logs, do tests or stuff, just let me know.
