Console Screen Saver and Backlight
Posted: Thu May 21, 2015 5:02 pm
I'm a long-time Linux user, but I'm new to Pi and Rasbian, so I need some help.
I have my Pi2 set up so that at the console, the screen saver kicks in after 10 minutes, and that's fine. But all that happens is the screen gets written with blanks. The backlight stays on, and there is no power saving as far as I can tell.
I've looked into /etc/kbd/config and I've setI've tried all four options for BLANK_DPMS to no avail. I get screen blanking after 10 minutes but the monitor never goes into sleep/suspend/power save mode. I feel like I'm missing something obvious and I've been googling for days but can't find a solution. (There are thousands and thousands of articles on how to stop the screen saver, but nothing much I can find on doing the opposite.)
I've noted utilities like tvservice, etc, and they work fine if I issue the appropriate command from the keyboard but that doesn't help with the automated screen saver.

Code: Select all
BLANK_TIME=10
POWERDOWN_TIME=15
BLANK_DPMS={on,vsync,hsync,off}
