Hi, and thanks for the answer. Anyway I was meaning that I had the usual startup screen of my N800 but without ANYTHING to click/press. From what I've read I was supposed to have KDE in my "extra" menu, but I couldn't do anything at all. I waited some minutes, let's say 5, after that I had to take off battery and reboot (= turn on again) the N800. This is why now I am really interested in installing KDE without MMC boot, you think it's not a good idea? Should I try again the MMC boot way? But it has to work, in both modes! I am wondering if my 2Gb MMC is not enough (for KDE with .debs), even if it seems me the most stupid answer to my problem. thanks again C.
