1. Enable Custom Touchpad setting (But seems only work with gnome-flashback&metacity)
	In /usr/share/X11/xorg.conf.d/51-synaptics-userdefined.conf
	Section "InputClass"
	    Identifier "touchpad catchall"
	    Driver "synaptics"
	    MatchIsTouchpad "on"

	    Option "PalmDetect" "true"
	    Option "HorizTwoFingerScroll" "true"
	    MatchDevicePath "/dev/input/event*"
	EndSection
2. Hibernate
	You have to use a swap partition
	and set /etc/default/grub CMD_LINUX resume=swappartition
	sudo pm-hibernate to test
	show the menu in gnome:sudo gedit /etc/polkit-1/localauthority/50-local.d/com.ubuntu.enable-hibernate.pkla
	paste following content and save it.

	[Re-enable hibernate by default in upower]
	Identity=unix-user:*
	Action=org.freedesktop.upower.hibernate
	ResultActive=yes

3. Clipboard history
	sudo apt-get install clipit

4. hpfall
	just make and put in /etc/rc.local

5. NVIDIA
	optirun xxxx use nvidia card to run program
	prime-select seems doesn't work(always use intel even selected nvidia)
6.HDMI
	https://zhuanlan.zhihu.com/p/133874045
	use intel-virtual-output to make HDMI work with bumblebee
	how does it works? /etc/X11/xorg.conf.d/20-intel.conf :

	Section "Device"
	    Identifier    "Intel Graphics"
	    Driver        "intel"
	    Option "VirtualHeads" "2"
	EndSection

	The most important is Option "VirtualHeads" "2"
	And some configuration in /etc/bumblebee/xorg.conf.nvidia

	Most important:
	Option "UseEDID" "true"
	#Option "UseDisplayDevice" "none"
	Option "AllowEmptyInitialConfiguration"
	#Option "ConnectedMonitor" "DFP"
	"AutoAddDevices" "true"

	Full config:

	Section "ServerLayout"
	    Identifier  "Layout0"
	    Option      "AutoAddDevices" "true"
	    Option      "AutoAddGPU" "false"
	EndSection

	Section "Device"
	    Identifier  "DiscreteNvidia"
	    Driver      "nvidia"
	    BusID       "PCI:01:00:0"
	    VendorName  "NVIDIA Corporation"

	#   If the X server does not automatically detect your VGA device,
	#   you can manually set it here.
	#   To get the BusID prop, run `lspci | egrep 'VGA|3D'` and input the data
	#   as you see in the commented example.
	#   This Setting may be needed in some platforms with more than one
	#   nvidia card, which may confuse the proprietary driver (e.g.,
	#   trying to take ownership of the wrong device). Also needed on Ubuntu 13.04.
	#   BusID "PCI:01:00:0"

	#   Setting ProbeAllGpus to false prevents the new proprietary driver
	#   instance spawned to try to control the integrated graphics card,
	#   which is already being managed outside bumblebee.
	#   This option doesn't hurt and it is required on platforms running
	#   more than one nvidia graphics card with the proprietary driver.
	#   (E.g. Macbook Pro pre-2010 with nVidia 9400M + 9600M GT).
	#   If this option is not set, the new Xorg may blacken the screen and
	#   render it unusable (unless you have some way to run killall Xorg).
	    Option "ProbeAllGpus" "false"

	    Option "NoLogo" "true"

	/etc/bumblebee/bumblebee.conf:
	KeepUnusedXServer=true
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
	/etc/systemd/system/hp-keycodes.service

	[Unit]
	Description=HP setkeycodes fix

	[Service]
	Type=oneshot
	Restart=no
	RemainAfterExit=no
	ExecStart=/usr/bin/setkeycodes e057 240 e058 240

	[Install]
	WantedBy=rescue.target
	WantedBy=multi-user.target
	WantedBy=graphical.target

	sudo systemctl daemon-reload
	sudo systemctl enable hp-keycodes.service

9. IPV4 First
	/etc/gai.conf
	uncomment precedence ::ffff:0:0/96  10
10. Lightdm numlock auto turn on
	/usr/share/lightdm/lightdm.conf.d/50-unity-greeter.conf
	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
	/etc/sysctl.conf
	fs.inotify.max_user_watches=524288
	(https://code.visualstudio.com/docs/setup/linux#_visual-studio-code-is-unable-to-watch-for-file-changes-in-this-large-workspace-error-enospc)

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.
16.backup /home

17.Enable SSH Forward X11
	/etc/ssh/ssh_config
	ForwardAgent yes

18.Let QT5 Program use GTK theme
	https://askubuntu.com/questions/706528/qt-apps-stopped-inheriting-gtk-themes/748186#748186
	Install qt5-style-plugins
	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
	sudo iptables -t nat -A OUTPUT -p tcp --dport 80 -j REDIRECT --to 1082
	To restore
	sudo iptables -t nat -F
20.trash-cli
	To prevent rm -rf
	sudo apt install trash-cli
	put alias rm='trash' in ~/.bashrc and /root/.bashrc
	1. Enable Custom Touchpad setting (But seems only work with gnome-flashback&metacity)
