[mythtv-users] Can't turn off screen blanking

[David Brodbeck]

Look on this page, under "Screen goes blank but returns when mouse is
moved or keyboard is used":
http://www.mythtv.org/docs/mythtv-HOWTO-22.html#ss22.4
Making the changes suggested there to my xorg.conf fixed the problem for
me.  I like this method better than messing around with xset.

You may also need to check your computer's BIOS settings for any screen
blanking settings there.
