LCD screen blank after a while

I have a mini2440 with 7" LCD.

I have the "mini2440_defconfig" home built kernel with debian on my system
and im trying to get qtopia running (more or less in the same way as on the
default image).

when i boot i see the logo and then i can start qtopia but after a while
the screen just blanks out. Perhaps the backlight turns off or something?
because the systems seems to be still running.

I guess its some sort of power saving, but how do i activate the screen
again?

The "problem" was that i have tty1 pointed to the LCD with a console login
on. And then the standard screen blanking got activated after a while.

There are probably a couple of different solutions to this but i added:
setterm -blank 0 > /dev/tty1 
to startup and it worked.

Erik, where do you add this setterm?

What file?

Thanks.

Can I ask a more basic question? What Linux commands do you use to point
tty1 to the LCD? And can you then send text and graphics by direct copying?
Thanks in advance.
