Hi guys !

I'm pretty new to Linux, so sorry if my question is pretty easy !!!

Here is my problem : I have a small target with Linux kernel (is 2.6.24.7) I've compil on it.

I'm building a small system with LCD and touch screen, no keyboard, no mouse, all display is done under framebuffer+SDL.

My problem is that after some minutes, the screen goes black, like if the kernel enter in screesaver mode ...

... I've look in my "make menuconfig" setup, by I haven't found the option ...

-> How could I disabling this ???
[Edit] Or maybe is it easier to simulate action with some C API ?

Thanks in advance.
