I'm running a Yocto build on an i.MX6 board and I'm trying to stop the screen from shutting off after 15 minutes of inactivity. I've tried the following things with no success:
- passing consoleblank=0 to bootargs
- modifying drivers/tty/vt/vt.c with static int blankinterval = 0;
Neither of these has had any effect.
cat /sys/module/kernel/parameters/consoleblank returns a value of 900.
My system does not have setterm.
