How to disable screensaver

contra — Thu, 10 Oct 2013 07:58:12 GMT

I am using the IMX28 build from LTIB to play video on the LCD. After approximately 10 minutes the screen goes blank but I can see through the console output that the video is still running. I believe that a screensaver is turning the display off. Is there a way to disable this?

Please try the following :

echo 0 > /sys/class/graphics/fb0/blank

frame buffer number (0 in the example) may differ.

Thanks for your reply, this did not stop the screensaver from turning on it seems to 'wake up' the display if the screensaver has come on.

It led me onto finding this:

echo -e '\033[9;0]' > /dev/tty1

I used this in a start up script and it seems to work.
