I recently updated to 18.04 and cannot boot using Xorg only Wayland. I have tried reinstalling xorg, reinstalling nvidia drivers, setting WaylandEnable=false in /etc/gdm/custom.conf but whenever trying to login using Xorg I get a frozen screen and mouse. I am using the latest nvidia-390 driver. My laptop has a dual graphics card ie. Intel and Nvidia. I would be fine staying with Wayland however it seems unstable and a dual monitor setup isn't working. Any thoughts what I can do to get this working so I can use Xorg .

You can try to inspect /var/log/Xorg.0.log.

I also had this issue. In my case, the reason was a corrupt file /etc/X11/xorg.conf.d/50-synaptics.conf which had the following line:

Example # xorg.conf.d que snippet assigns the touchpad driver

which was supposed to be:

# Example xorg.conf...

  • what were the symptoms (logs etc.) that lead you to where to look for the error?

  • I don't remember. That was 1.5 year ago. But I guess I found some clues in Xorg.0.log.

  • I gave up and reinstalled with 19.04. After disabling Nouveau at boot, the installer correctly installed an NVidia driver and now everything works.
