Run a script after killing lxsession (xorg)

Question

I am trying to run a program automatically within a bash script after killing the LXDE session. My script consists of:

#!/bin/sh
pkill lxsession;
sh /home/pi/RetroPie/EmulationStation/emulationstation

I tried this as well:

#!/bin/sh
nohup & pkill lxsession & 
writevt /dev/tty1 'emulationstation'

My aim is to log out of the LXDE session and run EmulationStation on my Raspberry Pi with a bash script. I'm using pkill lxsession; to bypass lxsession's logout confirmation dialog.

As it stands, this script just gets me to the command line from a working LXDE desktop. Thanks for reading.

Answer 1

I don't think that is possible. You run this script from a terminal emulator that is itself running within the LXDE session. When you kill the LXDE session, you also kill the terminal and, therefore, your script.

A possible workaround would be to log in via a different tty and run your script there. What exactly are you trying to do? Would a root cronjob work?

Answer 2

The writevt isn't available here, but I assume it just emulates tty input.

You could try starting a command in the tty before killing the X session, and have it wait until the X sessoin is killed. How about

#!/bin/sh
writevt /dev/tty1 'sleep 20s; emulationstation'` & 
pkill lxsession

Answer 3

Try using 'screen' when you either run the script from the terminal, or when you create a launcher:

screen ./emu-script.sh

screen will keep your terminal session alive even if LXDE kills, or whatever else you have shutdown. That way your script can finish properly
