@Benson: Extra repository is indeed present, as mentioned in my last post, but it only contains personal-menu, as mentioned earlier.

@qwerty12: The thread titled "HomeIP, HomeCPUSpeed, and HomeDiskFree" proposes a solution. But some pieces of the puzzle are missing:

1) The threads author, Khertan, mentions in post 41 that all "is fixed and should install straight forward without need to add an other package." By "other package" I assume he's referring to python-hildondesktop!?

But as you can see, I cannot run these still. So I am still following the thread's solution, which is as follows:

2) It is suggested to install python2.5-hildondesktop from extras-devel. But:
a) N810's App Manager contains Extra & Devel as two separate repositories and neither contain python2.5-hildondesktop
b) In 'All', however, there is "python-launcher" & "python2.5-edje-demo". Should I install one of these to get the applets to run?

Look forward to advise.
