NAME
mir_demo_server - Mir Display Server Demo
SYNOPSIS
mir_demo_server [options]
DESCRIPTION
Launch a Mir server demo session.
The Mir demo server 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_demo_server.config) is located via the XDG Base Directory Specification.
($XDG_CONFIG_HOME or $HOME/.config followed by $XDG_CONFIG_DIRS).
OPTIONS
--host-socket <socket-filename>
Host socket filename.
-f [ --file ] <filename>

/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.

--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).

--enable-key-repeat {0,1}
Enable server generated key repeat (default: 1).
--on-fatal-error-except

of a core dump).
--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 to run on or 0 to use current (default: 0).
Usage of this option requires --console-provider=vt
