<div>About the mail title, I would like disable blank screen on idle (it is happening to 10min). I've tried (found in another thread as solution):</div>
<div> </div>
<div>xset s off</div>
<div>xset -dpms <--- this isn't working, it shows "server doesn't have extension for -dpms option"</div>
<div>xset s noblank</div>
</div>

<p>* I'd suggest checking, through the GUI, your power and screensaver options.</p>
<p>* If you're plugged into an external screen, I'd also check *its* power options. (Especially if, like me, it's a TV-as-monitor.)</p>
