Lenovo E42-80安装Linux的注意事项
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_bluetooth
Soft blocked: no
Hard blocked: yes
1: phy0: ideapad_wlan
Soft blocked: no
Hard 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.
4. Engrampa压缩软件中文乱码的问题
由于Windows编码问题，Windows打包的压缩档在Linux下文件名可能显示为乱码，可以通过替换p7zip和unzip为patch之后的p7zip-natspec和unzip-natspec解决（archlinuxcn源），而仍使用Engrampa做前端。
发现一开始几篇随笔是用英语写的，大概是因为我汉语写起来废话太多，懒得重写，就几句话各位将就着看吧。。
