It can run in the background and be activated on demand to let you draw over all your currently running applications. The drawing will stay on screen as long as you want, you can continue to use your applications while the drawing is visible. .br \fBGromit-MPX\fP is XInput-Aware, so if you have a graphic tablet you can draw lines with different strength, colour, erase things, etc. .br Since you typically want to use the program you are demonstrating and highlighting something is a short interruption of you workflow, Gromit-MPX is activated by either a hotkey or a repeated invocation of Gromit-MPX (the latter can e.g. used by other applications or your windowmanager). .br .SH KEYBOARD CONTROL By default, Gromit-MPX grabs the "F9" key (this can be changed using the "\-\-key" option), making it unavailable to other application. The available shortcuts are: .TP .B F9 toggle painting .TP .B SHIFT-F9 clear screen .TP .B CTRL-F9 toggle visibility .TP .B ALT-F9 quit Gromit-MPX .PP .SH OPTIONS (STARTUP) A short summary of the available commandline arguments for invoking Gromit-MPX, see below for the options to control an already running Gromit-MPX process: .TP .B \-a, \-\-active start Gromit-MPX and immediately activate it. .TP .B \-d, \-\-debug gives some debug output. .TP .B \-k , \-\-key will change the key used to grab the mouse. can e.g. be "F9", "F12", "Control_R" or "Print". To determine the keysym for different keys you can use the \fBxev\fP(1) command. You can specify "none" to prevent Gromit-MPX from grabbing a key. .TP .B \-K , \-\-keycode will change the key used to grab the mouse. Under rare circumstances identifying the key with the keysym can fail. You can then use the keycode to specify the key uniquely. To determine the keycode for different keys you can use the \fBxev\fP(1) command. .TP .B \-o, \-\-opacity will set the initial opacity of the window using a floating point value between 0 and 1. .TP .B \-u , \-\-undo\-key will change the key used to undo/redo strokes. can e.g. be "F9", "F12", "Control_R" or "Print". To determine the keysym for different keys you can use the \fBxev\fP(1) command. You can specify "none" to prevent Gromit-MPX from grabbing a key. .TP .B \-U , \-\-undo\-keycode will change the key used to undo/redo strokes. Under rare circumstances identifying the key with the keysym can fail. You can then use the keycode to specify the key uniquely. To determine the keycode for different keys you can use the \fBxev\fP(1) command. .TP .B \-V, \-\-version will show the Gromit-MPX version. .SH OPTIONS (CONTROL) A sort summary of the available commandline arguments to control an already running Gromit-MPX process, see above for the options available to start Gromit-MPX. .TP .B \-c, \-\-clear will clear the screen. .TP .B \-q, \-\-quit will cause the main Gromit-MPX process to quit. .TP .B \-t, \-\-toggle will toggle the grabbing of the cursor. .TP .B \-v, \-\-visibility will toggle the visibility of the window. .TP .B \-y, \-\-redo will redo the last undone drawing stroke. .TP .B \-z, \-\-undo will undo the last drawing stroke. .SH ENVIRONMENT .TP .B XDG_CURRENT_DESKTOP Gromit-MPX uses this to determine which desktop environment it is running on. .TP .B XDG_CURRENT_SESSION Gromit-MPX uses this to determine whether is is running under X11 or Wayland. .TP .B XDG_CONFIG_HOME Directory to search for user's custom configuration file, defaults to .BI ~ /.config/ . .TP .B GDK_CORE_DEVICE_EVENTS If set, GDK does not use the XInput extension and only reacts to core X input events. This renders Gromit-MPX unusable, it will detect this and bail out with an error message. .SH FILES .TP .I gromit\-mpx.cfg Configuration file which defines pens and maps mouse buttons and modifiers to them. Searched for in user's custom configuration file directory and, if not found there, in .IR /etc/gromit\-mpx/ . .SH BUGS When there is no compositing manager such as Compiz, xcompmgr or Mutter running, Gromit-MPX falls back to a legacy drawing mode. This may drastically slow down your X-Server, especially when you draw very thin lines. It makes heavy use of the shape extension, which is quite expensive if you paint a complex pattern on screen. Especially terminal-programs tend to scroll incredibly slow if something is painted over their window. XFCE per default grabs Ctrl-F1 to Ctrl-F12 (switch to workspace 1-12) and Alt-F9 (minimize window) which renders Gromit-MPX's default hotkey mapping unusable. Gromit-MPX detects XFCE and changes the default hotkeys to Home and End. Those can can still be overridden by the user. .SH AUTHORS Simon Budig Christian Beier .PP This manual page was written by Pierre Chifflier and Simon Budig for the original Gromit and extended for Gromit-MPX by Christian Beier.
