I tried using few different distros on this laptop in last few years. I really like linux and want to use it in every day use but I have all sorts of problems on my laptop lenovo g500. Yesterday I finally decided to install it and make it work. For now I can't figure out how to make my hibrid gpu's switchable and I can't change my mac without breaking wifi totally (wifi just refuses to work even if I take it down via ifconfig, or even stopping the network-manager service, change mac, restart, still won't work). So I am hoping people here can help me.
First off, making hybrid GPUs switchable. I have integrated INTEL and discrete AMD gpu.
I followed HybridGraphics guide but when I try to echo any parameter to
/sys/kernel/debug/vgaswitcheroo/switch
for example
sudo echo IGD > /sys/kernel/debug/vgaswitcheroo/switch
Whatever parameter I use IGD/DIS/ON/OFF etc. Nothing happens.
Here's some info (command-result):

I am thinking that something might be wrong or that there simply is no driver for my amd gpu. But last year I think, I tried installing fglrx driver package and my ubuntu just keeps crashing then. Same with Fedora as well. Also when I check in "additional drivers" in system settings I am not getting any options for my amd card.
I have switchable graphics enabled in BIOS. I am using 16.04 ubuntu
