Cannot run Ubuntu 18.04 on Xorg

Question

My ideapad y520 was running Ubuntu 17.04 and recently I updated it to 18.04 from command line. However, I'm not able to boot into any desktop environment in Xorg mode. Only Wayland is working. Has anyone faced similar issue?

Solution

I had to uncomment 'WaylandEnable=false' in /etc/gdm3/custom.conf to be able to boot up. It worked, but I'd like to find a better fix for the situation. Booting up with 'WaylandEnable=false' commented out I would get stuck at gdm.servicegdm.service.

I hope this helps someone, I looked for this for a couple weeks.

Upgrading from 17.04 to 18.04 LTS is not likely to succeed. It is probably difficult to fix the problems. Try live, when booted from a USB pendrive made from an Ubuntu 18.04 LTS iso file. If it works well, please save your personal files to another drive and after that [maybe convert your original partition from the old 17.04 to a home partition and] make a fresh installation of 18.04 LTS.

I was having graphical glitches upon login in gdm3 on a MacBookPro12,1 running 18.04 with Xorg. Un-commenting the line above made this glitch go away.
