Wayland Platform
Requirements
The wl (Wayland) platform plug-in additionally requires the following
libraries and packages:
- WPEBackend-fdo
- Wayland
- libxkbcommon
- wayland-protocols
- wayland-scanner
Environment Variables
The following environment variables can be set to change how the Wayland surface used for output will be configured:
| Variable | Type | Default |
|---|---|---|
COG_PLATFORM_WL_VIEW_FULLSCREEN |
boolean | 0 |
COG_PLATFORM_WL_VIEW_MAXIMIZE |
boolean | 0 |
COG_PLATFORM_WL_VIEW_WIDTH |
number | 1024 |
COG_PLATFORM_WL_VIEW_HEIGHT |
number | 768 |
Setting COG_PLATFORM_WL_VIEW_FULLSCREEN will take precedence over
COG_PLATFORM_WL_VIEW_MAXIMIZE, and if either of those are enabled the size
specified with COG_PLATFORM_WL_VIEW_WIDTH and COG_PLATFORM_WL_VIEW_HEIGHT
will be ignored.
Note that these are requests made to the Wayland compositor, which has the final say in how the surface is presented to the user. In general, surfaces which have been fullscreened completely cover the output (i.e. they take the whole screen), while for maximized surfaces the compositor my still show some user interface elements (like borders or buttons) while trying to make the surface as big as possible. Some compositors take faster approaches when there is only a single fullscreen surface being displayed.
