I am not sure what Generation are those X1 laptops, so here are the specs: shop.lenovo.com/us/en/laptops/thinkpad/x-series/x1-carbon/#techspecs
Anyone with 14.04 would like to share his/her experience? I would like to buy one but couldn't find a lot of information about 14.04. Any issues and workarounds? Pablo mentioned 14.04 with 2nd Gen, but I am not sure what Generation are the recent X1.
