I’ve wondered about this myself too… As far as I know, PowerDevil is
the power manager for KDE4 and KPowerSave was for KDE3. In practice,
however, KPowerSave was used at least by openSUSE in KDE4 while
PowerDevil was still in development…
Anyways, this still leaves the display power management in two places
as you mentioned. I tried with different settings and it seems that the
timings in the “Display” section are the decisive ones and the timings
in PowerDevil do nothing. This is using KDE 4.2 RC1 from the build
service.
Additionally, one thing I came across with was that if I have
screensaver starting before the screen is supposed to go into power
saving, it seems that the screen won’t go to power saving state…
Anyone else seeing this?
