This is a bit off-topic, but important to anyone debugging screensaver
issues.. Xorg has two forms of screen blanking in addition to whatever
the screensavers provide, DPMS and "BlankTime". The latter is not a
power saving mode, it just makes the screen black to avoid burn in.
To disable both you need something like this:

Section "ServerFlags"
    Option "BlankTime" "0"
    Option "StandbyTime" "0"
    Option "SuspendTime" "0"
    Option "OffTime" "0"

The actual flags that need to be set depend on the Xorg version. Google
for them if this doesn't work.
