[nzlug] Blank screen wakeup (remotely)

[Raimund Eimann]

Hi,

I've got a Linux box without keyboard or mouse connected to my TV to play 
movies. The movies are started remotely.

When there has been no activity on the box, first the screen saver starts, and 
after a longer time the screen becomes black. If keyboard or mouse were 
connected, the blank screen would disappear immediately on a mouse movement 
or pressed key.

If the screen is blank and I start a movie remotely, the blank screen stays, 
although the movie starts (judging from the sound).

So far, I've been fixed this problem by switching virtual consoles with chvt:

... ; sudo chvt 1 ; sleep 1 ; sudo chvt 7 ; ...

Is there a more elegant way (like echo 1 >> /proc/<somefile>, or some 
command)?

Cheers,
Raimund
