Without X running, linux consoles blank after a period adjustable by setterm. Mine does not. It goes white. If I invert the screen colours, it goes whiter. Backlight? I cloned the Linus-stable git and tried it. 3.18.0-rc4 twists this slightly - The FIRST time the screen blanks, it does so correctly; every other time, it blanks to white. I'm a hardware guy, not a software expert. Git bisect gives the output below. Details of the box also attached
The box is a HP 6715S, twin core Turion, 3G ram. It's running Slackware-current as of Sept 30th, 2014. LSPCI output attached. Bios Version: ATI 02/13/08,1.
