I want to start backing up my Lubuntu 12.04 machine (on an HP Netbook) using the built-in Nepomuk service. It was recently upgraded from 11.10 and I dimly remember having the same problem a few months ago, though I did not do anything about it.
Anyway: When I try to open Nepomuk Backup, I get the following error message: "the Nepomuk backup service does not seem to be running"
Now, I would like to enable Nepomuk, but I cannot find the switch. I have googled for this problem, but it only brings up Ubuntu answers (like here) with lots of packet talk that I do not understand.
So here is my question: How do I enable Nepomuk? And - by extension - how do enable it at startup?
