Comment 8 for bug 2026790

I was unable to select the "Ubuntu on Xorg" as a configuration option, so I did it manually.

I modified /etc/gdm3/custom.conf

current configuration:

# GDM configuration storage
#
# See /usr/share/gdm/gdm.schemas for a list of available options.

[daemon]
# Uncomment the line below to force the login screen to use Xorg
WaylandEnable=false

# Enabling automatic login
# AutomaticLoginEnable = true
# AutomaticLogin = user1

# Enabling timed login
# TimedLoginEnable = true
# TimedLogin = user1
# TimedLoginDelay = 10

[security]
DisallowTCP=false

[xdmcp]
ServerArguments=-listen tcp

[chooser]

[debug]
# Uncomment the line below to turn on debugging
# More verbose logs
# Additionally lets the X server dump core if it crashes
Enable=true

This does not appear to work-around the problem. I am getting drm errors :
