 6.HDMI
 	https://zhuanlan.zhihu.com/p/133874045

 7. x0vnc
 	#This is a vnc server that can connect to current xserver session. It run automatically by gnome startup application. It listen :0(vnc port :5900) vnc port and use default vnc password.
 	Now I not use x0vnc, I use gnome setting->sharing->screen share to replace it.
 	But it need disable encryption, otherwise some vnc client like xrdp unable to connect:
 	dconf write /org/gnome/desktop/remote-access/require-encryption false

 8. Prevent turn on airplane mode when close lid

 	Add:
 	greeter-setup-script=/usr/bin/numlockx on
 11. v2ray
 	installed this https://github.com/jiangxufeng/v2rayL
 12.xrdp 
 	changed port to 63389. It can connect to -x0vnc-(127.0.0.1:5900) (now replace with gnome screen sharing)

 13. Modify file watchs for vscode

 14.ibus-rime
 	The main reason use this IME is wubi in ibus-table not good. In chrome unable to switch language, and all symbol in chinese mode is full size. worAnyway, not good.
 	rime is a very good workaround to use wubi. and config ~/.config/ibus/rime/default.yaml to make it only have "wubi86".

 14.nm-applet
 	It's gnome classic network manager system tray icon. It's easy to modify network setting and view net infomation. So put it in gnome startup application.

 15.disableNvidia.sh
 	It's use for restart nvidia card. I have put it in gist.

 	Add QT_QPA_PLATFORMTHEME=gtk2 to /etc/profile.d/appmenu-qt5.sh
 19.redsocks
 	It can work with iptables to redir all traffic to a socks5 proxy. /etc/redsock.conf config the port of socks5 proxy and redsocks proxy
 	I disabled autostart redsocks in systemd. So it need to start maunally: sudo systemctl start redsocks
 	To make all 80,443 OUTPUT to redsocks :
 	sudo iptables -t nat -A OUTPUT -p tcp --dport 443 -j REDIRECT --to 1082
