I'm curruntly running Mint/Xfce/32 Bits 18.3 on Lenovo Thinkpad X100e Single Core AMD 1.6Ghz/3Gb Ram/250Hdd. Works fine.
Already tested 64bits of many Linux distros, but they seen to lag (using 64bit) even though the processor offers 64bit support. Back in 2011 Lenovo recommended Ubuntu 10.04, maybe a little outdated nowadays.
Which version of Ubuntu is more suitable to run on this netbook? Using a non-LTS seen to be risky, so lets say it is my preference to keep on LTS flavors. I use this machine for casual browsing, writter, calc and scan some documents from a Hp 3050 Printer.
