I run some WIndows games via Wine in new x-window on tt8. Here is what I use

Exec=xinit '/home/deckoff/.PlayOnLinux/wineprefix/HOMM3/drive_c/Program Files/GOG.com/Heroes of Might and Magic 3 Complete/Heroes3' -- :1 -ac -depth 16

This will invoke script, which reads

!# /bin/bash



# sleep 4 

xrandr -s 640x480

# xrandr -s 1024x768 

/usr/share/playonlinux/playonlinux --run "ZumasRevenge.exe"

As you can see, I open a new x-windw and change resolution on the go. Sometimes, thoug, some of the games will freeze, and the x-window wont die, even if the game is closed.
Usually, I can kill x with ctr-alt-bkspace, but this will work in tt7(default) only. In tty8the command will not work.

So, I want to know, is there a way to restrat or kil the x-window process taking place in tty8
