Had this with nvidia graphics drivers after installing and then removing
proprietary drivers downloaded from nvidia website. I could not log in
at all at first boot.
If you see nvidia modules loaded, make sure that you select an xorg
session on the login screen (not wayland) if you this control presented
to you.
lsmod| grep nvidia
nvidia_uvm 794624 0
nvidia_drm 40960 13
nvidia_modeset 1040384 1 nvidia_drm
nvidia 17285120 653 nvidia_uvm,nvidia_modeset
ipmi_msghandler 102400 2 ipmi_devintf,nvidia
drm_kms_helper 172032 2 nvidia_drm,i915
drm 458752 13 drm_kms_helper,nvidia_drm,i915
Alternatively, just set WaylandEnable to false (and restart gdm).
cat /etc/gdm3/custom.conf
# ...
[daemon]
# Uncoment the line below to force the login screen to use Xorg
WaylandEnable=false
# ...
I also suspect that /etc/X11/xorg.conf generated by nvidia-xconfig
(which I ran during driver installation from the website) was causing
issues.
Steps I performed from a VT session:
1) sudo apt purge 'nvidia*'
2) reboot
3) sudo rm /etc/X11/xorg.conf
4) sudo apt install nvidia-driver-<version> nvidia-dkms-<version>
nvidia-settings nvidia-prime
5) reboot
I also have 11-nvidia-prime.conf file at /usr/share/X11/xorg.conf.d
which is generated by ubuntu-drivers-common:
cat /usr/share/X11/xorg.conf.d/11-nvidia-prime.conf
