I use xinit to start X with wm - startx command that using .xinitrc to invoke X11 environment, but when X starts, there a black screen with cursor staying there for few seconds before X is fully started and if I press ctrl-c to interrupt the process, it will drop to shell, meaning user always has a way to go into shell - how to disable this ability?

  • Did you try wm - startx & to run it as a background task? – Zhro Mar 5 at 3:51
  • @Zhro: I just use .profile to startx, what's difference with your command? I'll try and give feedback. – Tuyen Pham Mar 5 at 7:47

The issue here is that you're calling startx in the foreground. If you want it to run in the background and not be susceptible to ctrl-c then append & at the end of the command.

For example:

sleep 3s && echo 1

This command will sleep for three seconds and then echo 1 to standard output. As it is in the foreground, you can interrupt it with ctrl-c.

Alternatively, you can continue to work on other things in the foreground while it runs in the background until either you log out or it terminates:

sleep 3s && echo 1 &

If you are just running startx then try replacing it with startx &.
