Mounting /proc with hidepid=2,gid=sudo prevents X from starting properly. I originally reported the issue to Ubuntu in [1]. I'm using those mount options for added security/privacy.

On older releases this used to work fine.

Booting with hidepid=2 on a Fedora 28 machine, X starts with no problem. Presumably some other part of Ubuntu's setup is getting confused by this. It would be helpful if you could strace X startup to see why it doesn't think it can find the console.
