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'
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?
