I have a brand new, out of the box Lenovo Thinkpad 11e. I've installed 16.04 LTS using a USB, though I had to do this via the desktop of the 'try Ubuntu without installing' option as the screen would freeze on the regular install option. Now it's installed though, I'm having similar problems when trying to boot or shut down/restart (the screen will freeze, though it will boot eventually). I've ran all the updates, but that's not helped either. I've tried reinstalling, but the screen also freezes when trying both install options on the USB.
I've installed Ubuntu on multiple systems in the past and have never had a problem. Please help.
