![]() debugĮnable debug protocol extension weston_debug_v1 which any client can use to receive debugging messages from the compositor. If also -no-config is given, no configuration file will be read. If the path is not absolute, it will be searched in the normal config paths, see weston.ini(5). The argument can also be an absolute path starting with a /. The default backend is drm-backend.so unless the environment suggests otherwise, see DISPLAY and WAYLAND_DISPLAY. The file is searched for in /usr/lib64/weston, or you can pass an absolute path. ![]() Load backend.so instead of the default backend. Options Weston core options -B backend.so, -backend= backend.so ![]() It has also its own X window manager where cursor themes and sizes can be chosen using XCURSOR_PATH and XCURSOR_SIZE environment variables. When the first X client connects, Weston launches a special X server as a Wayland client to handle the X client and all future X clients. Weston starts listening on a new X display socket, and exports it in the environment variable DISPLAY. XWayland is activated by instructing weston to load the XWayland module, see Examples. XWayland provides backwards compatibility to X applications in a Wayland stack. This X server will connect to a Wayland server as a Wayland client, and X clients will connect to the X server. XWayland requires a special X.org server to be installed. IVI-shell starts with loading ivi-shell.so, and then a controller module which may launch helper clients. In-vehicle infotainment shell is a special purpose shell that exposes a GENIVI Layer Manager compatible API to controller modules, and a very simple shell protocol towards clients. The shell consists only of the shell plugin fullscreen-shell.so. The other compositor does not need to handle any platform-specifics like DRM/KMS or evdev/libinput. This is primarily intended for running another compositor on Weston. Fullscreen shellįullscreen shell is intended for a client that needs to take over whole outputs, often all outputs. Desktop shell consists of the shell plugin desktop-shell.so and the special client weston-desktop-shell which provides the wallpaper, panel, and screen locking dialog. Desktop shellĭesktop shell is like a modern X desktop environment, concentrating on traditional keyboard and mouse user interfaces and the familiar desktop-like window management. This means that a client must be specifically written for a shell protocol, otherwise it will not work. ShellsĮach of these shells have its own public protocol interface for clients. Each connecting client has its own seat making it a cheap way to test multi-seat support. Access to the desktop is done by using the RDP protocol. The RDP backend runs in memory without the need of graphical hardware. This is a cheap way to test multi-monitor support of a Wayland shell, desktop, or applications. Weston shows up as a single desktop window on the parent server. The Wayland backend runs on another Wayland server, a different Weston instance, for example. It supports multiple monitors in a unified desktop with DPMS. The DRM backend uses Linux KMS for output and evdev devices for input. Weston also supports X clients via XWayland, see below. Two plugins are provided: the desktop shell, and the kiosk shell. Weston supports fundamentally different graphical user interface paradigms via shell plugins. Weston has several backends as loadable modules: it can run on Linux KMS (kernel modesetting via DRM), as an X client, or inside another Wayland server instance. A Wayland server is a display server, a window manager, and a compositor all in one. Unfortunately we could not find a Composable that provides us the functionality to just add a new ComposeView to the Window so we copied the relevant parts and made following.Weston is the reference implementation of a Wayland server. What they do is add an entirely new ComposeView to the Window.īecause of this they are basically starting from a blank canvas.īy making it transparent it looks like the Dialog/Popup/DropDown appears on top. We faced similar issues and looked at the implementation how Composables such as Popup, DropDown and Dialog function. From what I can tell you want to be able to draw from a nested hierarchy without being limited by the parent constraints.
