How to set up X.org?

Question

linux

Installed X.org on a clean Ubuntu server, two questions arose about setting it up.
First, how can I make sure that when executing a command, the startxgraphical session starts in the seventh console (Ctrl + Alt + F7), and not in the one in which the command is typed?
Second, starting X.org starts Xterm, but how do you get something else to start, like Xfreerdp?

Answer 1

1. Nothing. startx - X test run method, which is used when testing, checking, crashing the DM. For regular work, it has not been used for years ... er ... fifteen.
2. When starting X through startx, the .xinitrc script is executed in the homework, respectively, all the commands that are in it will be executed. For example:

xautolock -time 15 -locker "xlock -mode dclock -messagefont 12x24bold -planfont 12x24 -font 12x24 -fg white -bg -black -time24" &
gnome-terminal --geometry $XGEOM+923+116 --title "X terminal" --hide-menubar &
gnome-terminal --geometry $XGEOM+185+49 --title "Root terminal" --hide-menubar -e "sudo tcsh" &
xhost +
exec starttde

Answer 2

1) it already runs on console 7
2) man .xinitrc
