I wiped the factory 14.04 install when I saw the number of error messages during updates. I&#x27;ve been running 16.04 daily builds, and the only perceptible issue (screen flicker&#x2F;blanking) was resolved  in 16.04 final. There&#x27;s a bios update which, although its release predates shipping, must be applied by users. (While still on factory 14.04, plonk the executable in &#x2F;boot&#x2F;EFI then reboot, F12, bios flash update).<p>Dell don&#x27;t appear to have updated their Ubuntu repositories for 16.04 but the necessary hardware drivers appear to be present in 4.4.x kernels. The same goes for Intel&#x27;s Linux driver tool, but this also works out of the box on 16.04.<p>I&#x27;m waiting for Amazon to deliver a USB 3.1-to-HDMI cable so I can test video out.
