Mageia forum

Hello,

If anyone could help, I would be very grateful.

I installed Mageia with KDE. But, within an hour or two the screen would dim. Then within a few seconds of using KDE and not interacting with the computer the desktop screen went blank.

How can I stop the KDE Desktop screen going into standby or off or dimming? Sorry, but I don't know the correct term.
The screen does not turn "off". All I have to do to get back to work is move the mouse and the KDE desktop appears.
But, I'm tired of the screen doing this. I thought it could be my monitor but I installed Xfce and have no problems.

I tried fixing this myself by:
- logging out of desktop
- logging in to terminal and deleting ~/.kde
- logging back in to KDE but no luck.

I believe I have all settings in the 'display' & also 'power management' areas of system settings set correctly ie. screensaver disabled, dim display after... disabled, turn off display after... disabled.
I see two places that can cause this in KDE:
1. Screen Saver Settings: Menu / Configure Desktop / Hardware / Display and Monitor / Screen Saver
2. Power Settings: Menu / Configure Desktop / Hardware / Power Management

Thank you.

you could try if

Code: Select all

xset s off

works for you, then will be possible to search a way to run it automatically at each startup

here somo more info:

http://linuxreviews.org/quicktips/screenblanking/index.html.en

Are you missing this in KDE system settings?

Hi tom_
the code you provided worked. Thank you.:

Code: Select all

xset s off

Hi dedanna1029, Yes, I have those settings. Thank you.
