Thank you, I was able to use “Alt + F2”, and it accepted my remove command for the script. I forgot to make my script to lock the screen on boot to be executable.
Simply forgot chmod +x script.
For a future reference, I’ve also modified my /etc/default/grub to have zero second time-out, so I am skipping the option to choose kernel and etc. Is there a key that can be pressed during/prior to boot to pop the menu up without the time out?
Also, what’s the latest version of the kernel that’s being used?
