I am REALLY sorry to write this, but all my efforts to install KDE on my N800 were without any success. I am using a 2Gb Sandisk MMC.

I tried first with the MMC card boot, following this instructions:

I was able to clone the OS to the card, and to boot from it, but when I was supposed just to click in the extra menu to start KDE, I had a blank screen without anything possible to do.

Ok. I restarted again. I said myself "let's try the easier way" ! I reflashed the N800 with the lastest firmware (maybe THIS is my error), read all this thread and install KDE on MMC without MMC boot. I downloaded the 4 files, checked the correct dimensions, and start install.
I didn't go too far.. When I tried to install the local-mmc1.deb file on my external MMC (or the local-mmc2.deb when I tried on the internal) it worked a bit and after it said "unable to install local-mmc1". I tried more than once, both internal and external MMC (of course with the proper files) but I didn't go beyond this step.

So I have just 2 ideas about my unsuccess:

1) The new firmware doesn't allow KDE installation
2) The 2Gb MMC is not big enough, even if freshly formatted.

What do you think? Should I reflash the tablet with the previous firmware ( -> reinstall all the apps!?) , buy an 4Gb MMC, or wait/give up?

Thanks to anybody who can help, all the best,

C.
