Arch specific issue on Lenovo Y520 ?

Dear all,

I recently by a Lenovo legion Y520 and of curse I install archlinux on it. I already installed ubuntu on my friends' laptop (and they have the same model). All laptop as the same issue. The rfkill show two module for wifi and bluetooth:

 $rfkill list
0: ideapad_wlan: Wireless LAN
	Soft blocked: no
	Hard blocked: yes
1: ideapad_bluetooth: Bluetooth
	Soft blocked: yes
	Hard blocked: yes
2: hci0: Bluetooth
	Soft blocked: yes
	Hard blocked: no
3: phy0: Wireless LAN
	Soft blocked: no
	Hard blocked: no

On this link: https://askubuntu.com/questions/929739/ … enovo-y520. They suggest the problem is coming from the ideapad_laptop module. I try it with a live ubuntu media on my laptop and the problem is fixed.  The problem is,when i unload this module in arch, the keyboard is not working anymore. I tryed blacklisting the other wifi module but they load anyway. When I just unload them, i cannot still remove the hardware block.

I have no clue how to solve this and I don't want to use any other distro but arch.

Thank for your reply,
Pop

Re: Arch specific issue on Lenovo Y520 ?

And does this result in any problems?

ip addr

I'd try the behavior of Fn+F7

Re: Arch specific issue on Lenovo Y520 ?

Hi Seth,

the command

 ip addr 

gave me the wifi interface correctly. However the interface is down and i could not set it up using ip link.

Finally,I blacklisted the module ideapad_laptop at boot and everything worked fine.  I still don't understand why the keyboard was not working when i did :

 modprobe -r ideapad_laptop 

.

This may be do to the fact that when the module is not blacklist there is also the module sparse_keyboard thatis loaded and requires ideapad_laptop whereas it is not loaded when ideapad_laptop is blacklisted.

Anyway, I like to try to blacklilst the other module that handle wifi to see which module is better to keep but I will close the topic.

If someone as the same issue just open a file /etc/modprobe.d/ideapad_laptop.conf, add

 /etc/modprobe.d/ideapad_laptop.conf
blacklist ideapad_laptop 

then reboot and it should be fine
