miral-system-compositor - Mir Display Server system compositor
miral-system-compositor [options]
miral-system-compositor is used for running
miral-shell or miral-kiosk nested and, if needed, under a
different user ID on top of a Wayland based desktop session.
Mir system compositor startup can be tweaked by:
- Command-line
options:
- e.g. "--host-socket=/tmp/mir_socket".
- Environment
variables:
- Capitalise the long form of the command line option, prefix it with
"MIR_SERVER_" and put "_" in place of "-".
E.g. "MIR_SERVER_HOST_SOCKET=/tmp/mir_socket".
- Config file
entries:
- Use the long form command line options in the configuration file. E.g.
"--host-socket=/tmp/mir_socket".
The config file (mir/mir-system-compositor.config) is located via
the XDG Base Directory Specification. ($XDG_CONFIG_HOME or $HOME/.config
followed by $XDG_CONFIG_DIRS).
- --host-socket
<socket-filename>
- Host socket filename.
- -f [ --file ]
<filename>
- Socket filename (default: $XDG_RUNTIME_DIR/mir_socket or
/tmp/<UID_NUMBER>-runtime-dir/mir_socket).
- --no-file
- Do not provide a socket filename for client connections.
- --arw-file
- Set socket file permissions to globally read-writeable (equivalent to
chmod a=rw).
- -p [ --prompt-file
]
- Provide a "..._trusted" filename for prompt helper
connections.
- --platform-graphics-lib
<platform_library>
- Library to use for platform graphics support (default: autodetect).
- --platform-input-lib
<input_library>

- --platform-path
arg (=/usr/lib/x86_64-linux-gnu/mir/server-platform)
- Directory to look for platform libraries (default:
/usr/lib/<multi-arch>/mir/server-platform).

{log,lttng,off} (=off)
- Compositor reporting, either of log, lttng or off
(default: off).
- --connector-report
{log,lttng,off}

off (default: off).
- --input-report
{log,lttng,off}
- How to handle to Input report, either of log, lttng or
off (default: off).
- --legacy-input-report
{log,off}

- How to handle the SharedLibraryProber report, either of log,
lttng or off (default: log).
- --shell-report
{log,off}
- How to handle the Shell report, either of log or off
(default: off).
- --composite-delay
<msecs>
- Compositor frame delay in milliseconds (how long to wait for new frames
from clients before compositing). Higher values result in lower latency
but risk causing frame skipping. A negative value means decide
automatically (default: 0).
- --name
<name>
- When nested, the name Mir uses when registering with the host.
- --nested-passthrough
{0,1}
- When nested, attempt to pass a client's graphics content directly to the
host to avoid a composition pass (default: 1).
- --offscreen
- Render to offscreen buffers instead of the real outputs.
- --enable-touchspots
- Display visualization of touchspots (e.g. for screencasting).
- --cursor
{auto,null,software}
- Cursor (mouse pointer) to use (default: auto).
- --enable-key-repeat
{0,1}
- Enable server generated key repeat (default: 1).
- --on-fatal-error-except

- --debug
- Enable extra development debugging. This is only interesting for people
doing Mir server or client development.
- --enable-mirclient
- Enable deprecated mirclient socket (for running old clients)
- --console-provider
arg (=auto)
- Console device handling how Mir handles console-related tasks (device
handling, VT switching, etc.) Possible values given:
- logind - use logind vt: use the Linux VT subsystem. Requires root
privileges.
- none - support no console-related tasks. Useful for nested
platforms which do not need raw device access and which don't have a VT
concept
- auto - detect the appropriate provider.
- --vt {0,1}
- VT to run on or 0 to use current (default: 0).
- Usage of this option requires --console-provider=vt
- --bypass

surfaces (default: 1).
- --x11-output
<sizes>
- [mir-on-X specific] Colon separated list of WIDTHxHEIGHT sizes for
"output" windows (default: 1280x1024).
- --wayland-host
<socket-name>
