14.3.15. How to switch off the screen saver and the blinking cursor?

Question:

I'm using a splash screen on my frame buffer display, but it is disturbed by a blinking cursor, and after a while the screen is blanked. How can I prevent this?

Answer:

Screen saver and blinking cursor can be turned off (and on) using escape sequences.

To turn off the screen saver, send the sequence "\E[9;0]" to the terminal ="/dev/tty1". For example, output the content of file "/etc/blank_off" in one of your init scripts:

# cat /etc/blank_off

To turn off the blinking cursor, send the sequence "\E[?25l\E[?1c" to the terminal. For example, copy the content of file "/etc/init_tty" to the terminal:

# cat /etc/init_tty
