Asus Zenbook UX410UA with memory extended to 16 GB. Works perfectly with Ubuntu but it's almost two years old so you can probably find something better. Although the only thing I'm missing is charging via USB-C (which it has but cannot use for charging). Everything else is excellent: the screen is beautiful, battery life is in the 10 hours range, the aluminium body is quite tough, and it doesn't get hot.
