I set my laptop to turn Blank in 10 mins, suspend to RAM in 1hr. in the Settings GUI but nothing happens.
Here’s what xset says:

Suspending by pushing the power button works and manually setting:
xset s dpms 1000 2000 3000
I started out with KDE but I really couldn’t stand KDE’s bizarre UI and ever increasing bloat. Yeah, it’s more configurable than Gnome: so much so that it is a confusing mess. After a month, I decided to run screaming back to Gnome.
I installed Gnome desktop, switched to it and everything seems fine except that the display will not blank and the system will not sleep.
It is very possible I uninstalled some package that KDE used for this purpose and failed to install whatever it is that Gnome uses.
