I am running the Debian wheezy beta and using my Pi to display my geckoboard dashboards using midori, as a result I want to prevent the screen from going blank, which it does after 10 minutes (though it doesn't seem to turn off the backlight). I have searched through the menu options and can not find how to prevent this. I came across a post on raspberrypi.org suggesting that the following:
sudo sh -c "TERM=linux setterm -blank 0 >/dev/tty0"
would solve the problem, but it does not work. I have also tried changing
BLANK_TIME to zero in
/etc/kbd/config without success.
