setterm --blank n allows me to configure the virtual terminal to automatically shut the display off after n minutes of inactivity. Unfortunately, I spend all my time in fbterm, where setterm does not apply.

I've found that I can manually shut the display off with

$ sudo sh -c 'echo 1 > /sys/devices/pci0000\:00/0000\:00\:10.0/0000\:02\:00.0/graphics/fb0/blank'

(and echo 0 to restore it).

Is there any way to detect periods of inactivity in the tty/fbterm, so that I can create a script to simulate a setterm --blank setting?

  • setterm command only work in /dev/tty* consoles, not from terminal emulators or terminal multiplexers. Commented Oct 27, 2017 at 17:35
  • Thanks! I've updated the question to reflect this understanding.
