What is the correct way to turn off the kernel's screen blanking? This is part of the VT driver and is totally independent of the X Window System's screen blanking and screensaver, so don't tell me about "xset dpms off" or the various xscreensaver options. The only way I've found to turn off the kernel's blanking is to log in on a virtual console and run "setterm -powersave off". If I forget to turn it off, the kernel will shut off my monitor while I'm actively working because the VT driver is unaware of keyboard and mouse acrivity that occurs in an X Window session.
Short of patching the kernel to disable that feature, is there a way to
disable it automatically when X is running? It would be nice to leave
it active when X is not running, but I'd be happy just to get rid of it.
Although it seems a bit of a hack, you could put the setterm line
in /etc/rc.d/rc.local and it should do what you want.
Unfortunately it doesn't seem to work unless I'm actually logged in on a virtual console. I've tried
setterm -t linux -powersave off </dev/tty1 >/dev/tty1 2>/dev/tty1
to no avail. Yes, the command was executed with root privileges. I've even run strace on it, and the command is doing its thing. It just doesn't appear to affect anything.

Maybe you need to set it in the actual X ttys? like TTY7 and 8?
