Set up VNC login without console login in Ubuntu Gnome environment

-

 It is said that GNOME does not support VNC connection without logging in by default.

So you have to do the following annoying task.


1) gnome-remote-desktop settings

Open "Settings" in gnome-remote-desktop, select "Sharing",

Find "Remote Desktop" or "Screen Sharing" and disable it. 


2) Install x11vnc

sudo apt update

sudo apt install x11vnc


3) Set x11vnc password

x11vnc -storepasswd


4) Set auto-start at boot (create x11vnc.service file)

sudo nano /etc/systemd/system/x11vnc.service


Contents

[Unit]

Description=Start x11vnc at startup

After=display-manager.service


[Service]

Type=oneshot

User=<username>

Group=<groupname>

ExecStart=/usr/bin/x11vnc -forever -usepw -display :0

RemainAfterExit=yes

Restart=on-failure


[Install]

WantedBy=multi-user.target


5) Apply

sudo systemctl daemon-reload

sudo systemctl enable x11vnc.service

sudo systemctl start x11vnc.service

sanitize on in CMakeLists.txt

-
1. CMakeLists.txt set(CMAKE_EXE_LINKER_FLAGS "${CMAKE_EXE_LINKER_FLAGS} -fsanitize=address") add_compile_options(-fsanitize=address) If a subdir is set with add_subdirectory and a module that does not support sanitize is imported from the path and needs to be removed, add -fno-sanitize=address to add_compile_options in CMakeLists.txt of the subdir to remove it. Basically, if you enable sanitize, sanitize will adjust ulimit's core to 0, so core will not occur. You can do this by putting the following part as an environment variable. (Below is the part you put in systemd's service) 2. service file in systemd [Service] LimitCORE=infinity Environment="ASAN_OPTIONS=handle_segv=0:handle_abort=1:abort_on_error=1:disable_coredump=0"
