It appears the kernel recognizes your Intel GPU with the 'i915' driver, but has failed to create a device for it. So your CPU is too new for this old Ubuntu release.
Please try the latest releases and tell us if the problem still occurs: 16.04.6: http://releases.ubuntu.com/16.04/ 18.04.2: http://releases.ubuntu.com/18.04/ ** Package changed: xorg (Ubuntu) => linux (Ubuntu) ** Changed in: linux (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xorg in Ubuntu. https://bugs.launchpad.net/bugs/1755237 Title: Missing graphic driver To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1755237/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
