Lubuntu with nothing changed. Works pretty well. Some system stuff, like the Software center and everything that has anything to do with managing packets and so on, are brutally slow for some reason, but otherwise it works very well. It's even snappy! And my wireless Logitec M305 which I thought was dead because windows doesn't recognize it? Works too. As well as the printer, just like that. I had to install some additional stuff to make the WLAN work though.
