Hi iPAS,
Believe it or not, I've seen this one too. See this website:
http://www.armadeus.com/wiki/index.php?title=FrameBuffer
Under Tips, you can find a way to wake the framebuffer from sleep:
echo 0 > /sys/class/graphics/fb0/blank
Or put the framebuffer in sleep mode:
echo 1 > /sys/class/graphics/fb0/blank
Or you can set the sleep timer (or disable it entirely):
echo -e '\033[9;X]' > /dev/tty1 (where X = time in minutes, or 0 for never go
to sleep)
