Can anybody of your guys test with Ubuntu. The X1 is not out yet in Germany. The windows 7 version should work quite well with Ubuntu, since it's no dedicated graphics card there should not be any problems with Ubuntu.
I've got an X1 Carbon running 12.04 without any significant hardware issues besides battery life. I only get 3-4 hours on a charge, but I've also not done any intense tuning as of yet.
