어떻게 해결한건지 정확히 모르겠다.
1) 우선 grub window에서 'E' 키를 누르고, network enable 설정, recovery mode로 부팅한 다음 apt-get install nvidia-384 를 실행한 덕분인지
(sudo service lightdm stop 는 실행안하고도 설치후 재부팅 하니까 잘 적용됬다.)
2) 아니면 다음 링크대로 수정한거 때문인지.

TODO : 다음 포맷때에는 1) 안 먼저해서 문제 해결되는지 확인하기.

아래방향 화살표 키캡을 분해했는데, 적어도 이건, 키캡 상단이 걸쇠(위쪽이 열려있고, 아래쪽이 막힌 ㄴ자 ) 에 걸려있고, 아래쪽이 snap-fit? 방식으로 걸려있음.
따라서 키캡 아래쪽을 먼저 scissor-switch 와 분해해야 걸쇠에 걸린 흰지가 안 부러짐.

Installing ubuntu on Legion Y520
This is a review for how I install ubuntu and drivers on Legion Y520.
1. Install ubuntu with usb boot disk .

2. Fix missing wireless connection
Thanks for https://askubuntu.com/questions/587743/wifi-hard-blocked/587760
When Install ubuntu 16.04 LTS at Legion Y520, OS can't detect wifi.
To fix this, just command
$ sudo tee /etc/modprobe.d/ideapad.conf <<< "blacklist ideapad_laptop"
and then reboot.
Before do that, "rfkill list" shows Wireless LAN hard blocked: Yes.
But after rebooting, no more hard block and no more problem with wifi.
That's all. Missing Wifi is fixed with just two commands.
3. Install nvidia driver (Update on 2018/ 4/ 17. Thanks to Leonardo Gonzales for comment.)
After connect internet (wifi or with ethernet wire), type following command
$ software-properties-gtk --open-tab=4
And select nvidia driver as follow.
This is also solution for freezing when shutdown/reboot/restart ubuntu 16.04.4.
When you try to shutdown ubuntu on cui-mode (ctrl+alt+f1), if you see message including "nouveau drm failed to idle channel ~~", then just installing nvidia driver instead of using xorg will solve your problem.
