Text-based Desktop Environment

Command-line options

Syntax

vtm [ -c <file> ][ -q ][ -p <id> ][ -s | -d | -m ][ -x <cmds> ]
vtm [ -c <file> ][ -q ][ -t | -g ][ -r [ <type> ]][ <args...> ]
vtm [ -c <file> ]  -l
vtm -i | -u | -a [mode] | -v | -?

<script relay via piped redirection> | vtm [ -p <id> ]

Without options, vtm runs Desktop Client, running an additional instance with Desktop Server in background if it is not running.

Option	Description
-h, -?, --help	Print command-line options.
-v, --version	Print version.
-l, --listconfig	Print configuration.
-t, --tui	Force TUI mode.
-g, --gui	Force GUI mode.
-i, --install	Perform system-wide installation. Allow Desktop Server to run in user context in Session 0 on Windows. Placing Desktop Server in Session 0 allows console applications to run independently of the user's GUI login session. Note: This prevents GUI applications from running from the vtm desktop environment. See "Session 0 Isolation" on the Web for details. Elevated privileges required.
-u, --uninstall	Perform system-wide deinstallation. Elevated privileges required.
-0, --session0	Use Session 0 to run Desktop Server in background. For Windows only.
-a, --mouse [mode]	Set/reset persistent access to mouse devices for all users on Linux platform (excluding Android). Run sudo vtm --mouse 0 to reset access. Elevated privileges required.
-q, --quiet	Disable logging.
-x, --script <cmds>	Specifies script commands to be run by the desktop when ready.
-c, --config <file>	Specifies a settings file to load or plain xml-data to merge.
-p, --pin <id>	Specifies the desktop id it will be pinned to.
-s, --server	Run Desktop Server.
-d, --daemon	Run Desktop Server in background.
-m, --monitor	Run Log Monitor.
-r, --, --run	Run desktop applet standalone.
<type>	Desktop applet to run.
<args...>	Desktop applet arguments.
--env <var=val>	Set environment variable.
--cwd <path>	Set current working directory.
--fonts [v[erbose]]	Print available fonts (with horizontal scrolling).

Inline configuration

The plain xml-data could be specified in place of <file> in --config <file> option:

• command-line:

  vtm -c "<config><terminal><scrollback size=1000000/></terminal></config>" -r term

  or (using compact syntax)
• command-line:

  vtm -c "<config/terminal/scrollback size=1000000/>" -r term

Linux VGA Console (in-kernel console)

In order to use a mouse or touchpad in Linux VGA Console, you must grant the user access to mouse/pointing devices. By default, only privileged users and users of the input group have access. To grant all users permanent access to all pointing devices, use the command:

• sudo vtm --mouse
  

To reset permanent access, use the command:

• sudo vtm --mouse 0
  

Desktop Applets

Applet	Type	Arguments
Teletype Console (default)	vtty	CUI application with arguments to run
Terminal Console	term	CUI application with arguments to run
DirectVT Gateway	dtvt	DirectVT-aware application to run
DirectVT Gateway with TTY	dtty	CUI application to run, forwarding DirectVT I/O

The following commands have a short form:

• vtm -r vtty <cui_app...> can be shortened to vtm <cui_app...>.
• vtm -r dtty ssh <user@host dtvt_app...> can be shortened to vtm ssh <user@host dtvt_app...>.

Scripting

Script Command	Description
vtm.desktop.Run([{ <attr_list...> }])	Create and run a menu item constructed using a comma-separated list of <attribute>=<value> (derived from existing or updated temporary item).
