Thanks for the bug report. As far as I can tell, the system is trying to
use Xorg by default because Nvidia is the primary GPU(?), but the Nvidia
Xorg driver is not properly installed (according to the Xorg log it's
not present).

Please try using the 'Additional Drivers' app to reinstall an Nvidia
driver.

Also if you remove the 'nomodeset' kernel parameter then you would also
have the option of selecting 'Ubuntu on Wayland' at the login screen.

Title:
  Xorg freeze

Status in Ubuntu:
  Incomplete

Bug description:
  On every boot, system starts gdm.service but fails to load graphical
  login interface. Instead, black screen with cursor appears, flashes
  about 3 or 4 times, then hangs on a black screen with flashing cursor.
  From this screen, I can Ctrl+Alt+F2 into tty2 and login. In order to
  load the graphical login screen, I must run `sudo apt purge gdm3`,
  `sudo apt install gdm3`, then `sudo systemctl restart gdm.service`.
  Attempting to restart gdm.service BEFORE purging and reinstalling gdm3
  only sends me back to the flashing cursor screen. I have tried
  uncommenting the line `#WaylandEnable=false` in /etc/gdm3/custom.conf,
  but this does not appear to change anything. Also, for every fresh
  boot, I must repeat this process.
