Lenovo E42-80安装Linux的注意事项

https://www.cnblogs.com/dylanchu/p/9750760.html

1. 用U盘做个liveCD

While making usb installing media, do not use "UltraISO", it would not work.

Use command "dd" or 'usbwriter'(1xx KB) under windows.

2. 如何开启WiFi (kernel version < 4.18)

更新：
如果你安装的发型版Linux内核在4.18及以上，可以直接跳过这步。我已经提交了E42-80的网卡驱动补丁，并被整合到Linux4.18-rc1及之后的内核中。

After setup the wlan hardware is not able to use. While execute "sudo rfkill list all" you will see

    ...0: hci0: ideapad_bluetoothSoft blocked: noHard blocked: yes1: phy0: ideapad_wlanSoft blocked: noHard blocked: yes...

And wlan cannot be enabled. Also sudo rfkill unblock all won't solve that.

To solve this, you need to edit two files:

sudo vi /etc/modprobe.d/ath10k_core.conf--- then make sure "options ath10k_core skip_otp=n"
sudo vi /etc/modprobe.d/ideapad_laptop_blacklist.conf--- add line "blacklist ideapad_laptop", save and quit.

Reboot and you will find wlan and bluetooth are ready to use.
(Driver /lib/firmware/ath10k/QCA9377/hw1.0/ is already there but it's blocked by ideapad_laptop by default)

3. 显卡的注意事项

显卡驱动不要使用video-vesa !

Manjaro settings manager allows you to install or uninstall hardwares' drivers easily via GUI. But just be aware that on lenovo E42-80 you should use the graphics card driver video-linux instead of video-vesa. Once video-vesa is installed and you reboot your pc, you'll find your desktop would split into two part which left and right are swithed.
