[PATCH] vt: disable console blanking by default

From: Tomasz Torcz
Date: Wed Jun 18 2014 - 05:18:06 EST


Remove default 10 minute blank interval. Instead: never blank by
default.
"Screensaving" is no longer useful. Today it only provides
obstacle when interacting with text console, especially through
remote lights-out management solutions.
