NAME

miral-shell - Mir Display Server shell

SYNOPSIS

miral-shell [options]

DESCRIPTION

miral-shell launches a Mir Display Server shell, offering both traditional and tiling window management.

The Mir shell 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>

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).
