--- Comment #16 from Oliver Winker oliverml1@oli1170.net 2011-11-13 02:54:20 PST --- As a workaround in the meanwhile, I deactivated the KDE screen power-mgmt and just use an initial "xset dpms 240 0 0", which just triggers a "stand-by" after 240sec and no "suspend". This works without problems (stand-by and wakeup from).

Anyway, I will also retry a bit and do some testing using "suspend" on a 3.1, to see if something changed.
