Well, until today i had no (fatal) issues i couldn't deal with... i guess there is always a first time

Anyway, finding the exact package is a problem - i tried reverting to my oldest backup (about a month ago) and could still see the problem there which i find to be quite strange, since this entire month i did not have this issue (and i restarted the device several times during). That is why my first instinct was to assume that it is a hardware issue, but then i investigated and found the issue with hildon-desktop process not being loaded, and that is probably the only issue right now - to make it load the way it did before.
