You can enable / disable the screensaver easily without unloading any module.
Disable Screensaver:
Code:
lipc-set-prop com.lab126.powerd preventScreenSaver 1
Enable Screensaver:
Code:
lipc-set-prop com.lab126.powerd preventScreenSaver 0
There already exists a disable script "ds.sh" in /usr/bin which contains just the above line.
Add a corresponding enable script, add both (or the direct calls) to the GUI launcher or enable them as command for the "search field" and you're finished...
Easy - and no need to load / unload modules
