Is it possible to send a command from the console, say tty1, to the terminal currently occupied with X (in my case tty7 as I use Debian), to tell for example mplayer to play a movie?Edit - made a shorthand function with the commands I learned in the answer below:function movie () {  ORIG_TTY=`fgconsole`  chvt 7  DISPLAY=:0 mplayer -fs $1 > /dev/null 2> /dev/null  chvt $ORIG_TTY}
Send a command from the console to a running X server
command line;x11;console;remote
I'm exactly sure about what you are looking for. But to launch a new application inside a running X server you can use for example:DISPLAY=:0 mplayer -fs video.oggYou can choose the id of the X server, and you may add an optional screen identifier like :0.1 to launch the application in screen number 1.
