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

    I think you can kill x-window with Alt + sys-rq + K .

  • It is a keyboard key. See an example: imgur.com/iaoJC

  • Alt+PrintScreen+K - got it. This works. Anyway, I wrote a script, which can be used to kill Xorg at tty8. With some effort, it can be easily modified to kill anything at any tty :) Here it is<br /> #! /bin/bash JOB=$(ps -A | grep -w 'tty8' | grep -w 'Xorg') JOBNUMBER=$(echo $JOB | awk 'BEGIN { } ; {print $1}') kill -9 $JOBNUMBER

  • Glad it works. So I will post as an answer if someone come here with the same problem.

You can use the key combination Alt + SysRq + K.

SysRq is often the Print Screen key.

  • That killed all the windows and logged out of the window manager...thanks :P May 15 '13 at 18:22

  • Doesn't work in 14.04. PrtScr is a Fn key on my laptop if that matters.

  • Yes it matters. You probably have to add the Fn key to the combination above.

Alt + F2

gksu xkill

you click on the window you want to close.

Also you could try with terminal lets say banshee is stuck when you tried to listen an online radio station..

sudo ps -A|grep bans
>10304  bla bla bla
^ the result of the command
sudo kill 10304

you could try sudo kill -s kill 10304.

a more easy way

gksu gnome-system-monitor

this is all you need to know.

    This will work most of the time, this is why I accept this answer. In this current case the app is working on its on in the new X window, so alt+f2 cannot bring command line :)

Try the following in a terminal:

echo "setxkbmap -option terminate:ctrl_alt_bksp" >> ~/.xinitrc

The file .xinitrc in your home folder should be read every time X is started either via startxor xinit, and the option we just added should enable "zapping" the server.

  • No, nothing happens, I added it, checked the file, the was correctly changed, restarted, but still this key combination will not work. I think I can write a simple bash script to find xorg process running at tty8 and kill it. kill -9 some number will kill it
