Blank Screen after short period of inactivity


I'm running Debian etch and a couple of weeks ago, my screen (laptop) now goes blank after a few minutes of inactivity, it never used to do this. I checked the settings for the screensaver and power management and I have them set not to use any screensaver and to never turn off the monitor.

Today, I removed gnome-screensaver, but that didn't help. Any ideas on why this is happening and how to correct?

It does seem to have standby, suspend and off set. But in my Gnome preferences, I see that I have it set to "Never".

xset -dpms

I now get

I left my computer and came back to a black screen again.

Try this instead:
Code:
xset -dpms s off
The "s off" part should turn the screen-blanking screensaver mode off.

That seems to do the trick. I will lose this after I log off or reboot, correct? How would I have this set always?

Anyone know why this started to happen? Like I said, it only started a couple of weeks ago.
