xdg-desktop-portal-wlr - an xdg-desktop-portal backend for wlroots
xdg-desktop-portal-wlr (or xdpw for short) allows applications to request screenshots and screencasts via xdg-desktop-portal in wlroots-based Wayland compositors. xdpw will try to load the configuration file from these locations: • $XDG_CONFIG_HOME/xdg-desktop-portal-wlr/$XDG_CURRENT_DESKTOP • $XDG_CONFIG_HOME/xdg-desktop-portal-wlr/config • /etc/xdg/xdg-desktop-portal-wlr/$XDG_CURRENT_DESKTOP • /etc/xdg/xdg-desktop-portal-wlr/config $XDG_CONFIG_HOME defaults to ~/.config. $XDG_CURRENT_DESKTOP can be a colon separated list. Each element of that list will be tried. The configuration files use the INI file format. Example: [screencast] output_name=HDMI-A-1 max_fps=30 exec_before=disable_notifications.sh exec_after=enable_notifications.sh chooser_type=simple chooser_cmd=slurp -f %o -or
These options need to be placed under the [screencast] section. output_name = name Select which output will be screencast. This option is used with chooser_type = none. The list of available outputs can be obtained via wayland-info(1) (under the zxdg_output_manager_v1 section). max_fps = limit Limit the number of frames per second to the provided rate. This is useful to reduce CPU usage when capturing frames at the output's refresh rate is unnecessary. exec_before = command Execute command before starting a screencast. The command will be executed within sh. exec_after = command Execute command after ending all screencasts. The command will be executed within sh. chooser_cmd = command Run this command to select an output. For more details see OUTPUT CHOOSER. chooser_type = type Specifies the input send to the chooser. The supported types are: • default: xdpw will try to use the first chooser found in the list of hardcoded choosers (slurp, wofi, bemenu) and will fallback to an arbitrary output if none of those were found. • none: xdpw will allow screencast either on the output given by output_name, or if empty an arbitrary output without further interaction. • simple, dmenu: xdpw will launch the chooser given by chooser_cmd. For more details see OUTPUT CHOOSER. force_mod_linear = bool Force buffers with implicit modifiers to be linear (experimental) Setting this option to 1 will force xdpw to allocate dma-bufs with implicit modifier as linear. This option shouldn't be required on single gpu setups, but can increase compatibility especially on setups with multiple gpus. This option is experimental and can be removed or replaced in future versions. OUTPUT CHOOSER The chooser can be any program or script with the following behaviour: • It returns any error code except 127. The error code 127 is internally used to signal that no command could be found and all output from it will be ignored. • It returns the name of a valid output on stdout as given by wayland-info(1). Everything else will be handled as declined by the user. • To signal that the user has declined screencast, the chooser should exit without anything on stdout. Supported types of choosers via the chooser_type option: • simple: the chooser is just called without anything further on stdin. • dmenu: the chooser receives a newline separated list (dmenu style) of outputs on stdin.
