Arch:安装VNC

sudo pacman -S tigervnc
vncpasswd

# ~/.vnc/config

session=plasma
geometry=1920x1080
# localhost
# only accepts connection from localhost
alwaysshared

# /etc/tigervnc/vncserver.users
:1=riguz

systectl start vncserver@:1.service

应为tigervnc的登录认证不是很安全，推荐的做法是只允许localhost，然后通过ssh隧道连接

ssh 10.226.31.2 -L 5901:localhost:5901
vncviewer localhost:1

Ubuntu

sudo apt-get install tigervnc-standalone-server tigervnc-xorg-extension tigervnc-viewer
sudo apt install xterm

# vncserver will fail!
Session startup via '/etc/X11/Xtigervnc-session' cleanly exited too early (< 3 seconds)!

Maybe try something simple first, e.g.,
	tigervncserver -xstartup /usr/bin/xterm
The Xtigervnc server cleanly exited!
The X session cleanly exited!

tigervncserver -xstartup /usr/bin/xterm
vncserver -list
