Public bug reported: Updating to linux-image-4.15.0-34-generic broke X at start-up.
[ 157.020] (II) systemd-logind: logind integration requires -keeptty and -keeptty was not provided, disabling logind integration [ 157.021] (II) xfree86: Adding drm device (/dev/dri/card0) [ 157.021] (EE) /dev/dri/card0: failed to set DRM interface version 1.4: Permission denied [ 157.035] (EE) Screen 0 deleted because of no matching config section.

Reverting back to linux-image-4.15.0-33-generic fixed it. By the way, the failsafe X did not offer this option and nothing offered worked for me. This felt like being back in the 90s...
