I could find that /sys/module/kernel/parameters/consoleblank is the place where the screen blank time is present and "echo -e '\033[9;0]' > /dev/tty1" will reduce that time to 0 which basically means screen will never go blank. For me the default value is 600 which basically means after 10 mins of inactivity, the screen goes blank. But i am trying to understand couple of things.
1. What are the "activities" that reset this timer ?
2. Can we control this timer from user space ? If so, how can we ?
Can anyone help me with any kind of guidance or documentation or links ?
Thank you for your time.

Hi Igor,
Thanks for the link. But i have already gone through the link and i coundn't find my answers there. This is one another link where i could find the tty "commands" to modify the screen configurations.
