I have disabled all energy saving settings for my display in system settings (see screenshot) but my screen still keeps blanking after a few minutes. Where can I disable this additional setting? I cannot seem to find anything, energy saving settings are also all disabled in BIOS-setup, it’s not a BIOS issue either. Talking about openSUSE 11 with KDE 4.0.4 here.
this is nagging me since 10.x, the only way I found is to start sax2 and disable DPMS for the display.

Thank you! That did indeed solve the problem. I can even use the energy saving settings now because they actually do work once DPMS is disabled

Xwindows defaults to blanking the screen after 600 seconds (10 minutes)
Can be changed with the xset command:
set no blanking ever
xset s off
set blanking after 3 minutes
xset s 180
xset also handles DPMS settings
turn dpms off entirely
enable dpms with Xserver defaults
set dpms for standby after 30 minutes, suspend after 45 minutes and off
after 60 minutes
xset dpms 1800 2700 3600
remember, ALL times are from ‘zero’, and must be ascending if specified.
standby <= suspend <= off
the xset man page has more information, and there are many more options to
tweak. (‘xset q’ is very useful)

In case you have a text mode installation you can add the following to /etc/init.d/boot.local:
setterm -blank 0
setterm -powersave off
setterm -powerdown 0
More info in the man pages for setterm.
