NAME

       wayvnc - A VNC server for wlroots based Wayland compositors.

SYNOPSIS

       wayvnc [options] [address [port]]

OPTIONS

       -C, --config=<path>
           Select a config file.

       -o, --output=<name>
           Select output to capture.

       -k, --keyboard=<layout>[-variant]
           Select keyboard layout. The variant can be appended if needed.

       -s, --seat=<name>
           Select seat by name.

       -r, --render-cursor
           Enable overlay cursor rendering.

       -f, --max-fps=<fps>
           Set the rate limit (default 30).

       -p, --show-performance
           Show performance counters.

       -u, --unix-socket
           Create a UNIX domain socket instead of TCP, treating the address as a path.

       -d, --disable-input
           Disable all remote input. This allows using wayvnc without compositor support of
           virtual mouse / keyboard protocols.

       -V, --version
           Show version info.

       -h, --help
           Get help.

DESCRIPTION

       This is a VNC server for wlroots based Wayland compositors. It attaches to a running
       Wayland session, creates virtual input devices and exposes a single display via the RFB
       protocol. The Wayland session may be a headless one, so it is also possible to run wayvnc
       without a physical display attached.

CONFIGURATION

       wayvnc searches for a config file in the location
           ~/$XDG_CONFIG_HOME/wayvnc/config
       or if $XDG_CONFIG_HOME is not set
           ~/.config/wayvnc/config

   SYNTAX
       The configuration file is composed of key-value pairs separated with an equal sign.
       Whitespace around either the key or the value is insignificant and is not considered to be
       part of the key or the value.

   KEYWORDS
       address
           The address to which the server shall bind, e.g. 0.0.0.0 or localhost.

       certificate_file
           The path to the certificate file for encryption. Only applicable when
           enable_auth=true.

       enable_auth
           Enable authentication and encryption. Setting this value to true requires also setting
           certificate_file, private_key_file, username and password.

       password
           Choose a password for authentication.

       port
           The port to which the server shall bind. Default is 5900.

       private_key_file
           The path to the private key file for encryption. Only applicable when
           enable_auth=true.

       username
           Choose a username for authentication.

       xkb_layout
           The keyboard layout to use for key code lookup.

           Default: XKB_DEFAULT_LAYOUT or system default.

       xkb_model
           The keyboard model by which to interpret keycodes and LEDs.

           Default: "pc105"

       xkb_options
           A comma separated list of options, through which the user specifies non-layout related
           preferences such as which key is the Compose key.

           Default: XKB_DEFAULT_OPTIONS or system default.

       xkb_rules
           The rules file describes how to interpret the values of the model, layout, variant and
           options fields.

           Default: XKB_DEFAULT_RULES or system default.

       xkb_variant
           The keyboard variant to use for keycode lookup.

           Default: XKB_DEFAULT_VARIANT or system default.

   EXAMPLE
           address=0.0.0.0
           enable_auth=true
           username=luser
           password=p455w0rd
           private_key_file=/path/to/key.pem
           certificate_file=/path/to/cert.pem

ENVIRONMENT

       The following environment variables have an effect on wayvnc:

       WAYLAND_DISPLAY
           Specifies the name of the Wayland display that the compositor to which wayvnc shall
           bind is running on.

       XDG_CONFIG_HOME
           Specifies the location of configuration files.

FAQ

       How can I run wayvnc in headless mode/over an SSH session?

           Set the environment variables WLR_BACKENDS=headless and WLR_LIBINPUT_NO_DEVICES=1
           before starting the compositor, then run wayvnc as normal.

       How can I pass my mod-key from Sway to the remote desktop session?

           Create an almost empty mode in your sway config. Example:
               mode passthrough {
                    bindsym $mod+Pause mode default
               }
               bindsym $mod+Pause mode passthrough
           This makes it so that when you press $mod+Pause, all keybindings, except the one to
           switch back, are disabled.

       Not all symbols show up when I'm typing. What can I do to fix this?

           Try setting the keyboard layout in wayvnc to the one that most closely matches the
           keyboard layout that you're using on the client side. An exact layout isn't needed,
           just one that has all the symbols that you use.

       How do I enable the Compose key?

           Set "xkb_options=compose:menu" in the config file. Any key that is not otherwise used
           will work. There just needs to be some key for wayvnc to match against.
