Screenblanker
 
Hello,

The last week I've been trying to disable the screen going blank. I've found several suggestions via google, but none seem to work.
What I've tried:
Disabled KDE screensaver.
added consoleblank=0 kernel option to lilo.conf
Change rc.M to: setterm -blank 0 -powersave off -powerdown 0 &
Added a script to kde-startup with:
Code:
#!/bin/sh
xset -dpms &
xset s noblank &
xset s off &
Tried both at boot and pre-boot.

But my screen keeps going blank when I watch something on Youtube, or while having a skype call.
How do I disable this?!

What Slackware/KDE version are you using? If it is 14.0 or later you should disable power management (e.g. by unchecking the checkbox in the KDE Battery Monitor dialog.)

Sorry, I'm on Slackware64 14.0 with kde 4.10.4.

Omg, thanks. I been looking at the wrong place. I didn't look at power management. I just turned of the screensaver at the Display&monitor settings. I hope I can do my stuff now without the screen blanking on me!

Hehe, no worries. I was puzzling that too for some time before it dawned on me that KDE is doing screensaving as part of its power management.

I had the same issue and it drove me bonkers because it prevented me from watching Netflix. Turning power management off didn't solve my issue for whatever reason. I ended up turning power management 'on' then changing 'dim display' and 'switch off display' to their maximum settings of 360 minutes.

Tho' the issue is solved, there is another setting (affecting the screensaver) that *finally* worked for me in the past:

Code:
xset s noexpose
from 'man xset'

Quote:
The 'expose' flag sets the preference to allow window
exposures (the server can freely discard window contents),
while 'noexpose' sets the preference to disable screen saver
unless the server can regenerate the screens without causing
exposure events.
cheers,

It drove me nuts too. How not looking at the right place can affect us lol. It does work for me though to turn power management off, gladly.
