Although I dislike KDE, and have therefore never become thoroughly familiar with it (as I'd preferred GNOME when I'd wanted and needed a full-service distro), I've gone ahead and loaded this KDE hack on my N800. I have not upgraded the operating system, and I've installed KDE on a 2gb card in the external slot. (I have OPEN-ROX on the internal slot.) I find the 2gb card is so far allowing me plenty of memory space. However, I also encountered the same crash during the KDE panel init, even upon repeated rebootings and running the stopmaemo. I had also previously modified the af-services file. Other than that, my KDE installation seems to still have some limited functionality, and I will be watching this thread closely to see what you more experienced Linux hands are able to resolve. I regret that my expertise does not go far enough for me to be able to lend a helping hand. I will wait expectantly though on the sidelines. Many thanks again for your efforts.
