I want to execute cmatrix in my TTY for when I connect my Raspberry Pi to a monitor by default. I found a .service file here, and I'm wondering if it could work in my case.
Again, I just want cmatrix to run automatically on boot before the TTY login, but when I press q, the TTY login shows up, and that's about it.
Can the answer linked above work for me before I screw up my system?
Yes, I had same needs with my Raspberry 3B and 3.5" monitor that doesn't go on screen blank.
Create the file
/root/loginMatrix.sh
and give execute permissions
chmod ug+x /root/loginMatrix.sh
create the file
/etc/systemd/system/getty@tty1.service.d/override.conf
with the following content
[Service]
ExecStart=
ExecStart=-/root/loginMatrix.sh
StandardInput=tty
StandardOutput=tty
then activate it
systemctl daemon-reload; systemctl restart getty@tty1.service
or reboot.
You'll have cmatrix as screen saver, and just press a key to have login prompt. Doing CTRL+D to exit from session and you'll see cmatrix again.
