From cb8889206ccd1bba415637cab83e4ef38fd74b1e Mon Sep 17 00:00:00 2001 From: Hans Verkuil Date: Sun, 19 Oct 2008 23:58:26 +0200 Subject: ivtvfb: FB_BLANK_POWERDOWN turns off video output From: Ian Armstrong When using FBIOBLANK, FB_BLANK_POWERDOWN will now switch off the video output. Since some televisions turn themselves off after a while with no signal, this is the closest we can get to power-saving.
