[lug] Screen blanking

[Daniel Webb]

So I'm trying to figure out how to get a laptop to never blank the screen so I
can use it as a picture frame.  How many different places are there that can
cause the screen to blank?  It is a Thinkpad and I have the Thinkpad modules
loaded and everything turned off using tpctl, but it still blanks (real
console and X11 too).  So I'm assuming this isn't at the X11 level, but I
don't know where to look.
