Unable to login to account in ubuntu 18.04 vmware workstation 15, after update
The issue is with Wayland. While Ubuntu defaults to an X11 session, for some reason they left it enabled for GDM.
You can certainly replace GDM with LightDM, but an easier option would be to:
sudo nano /etc/gdm3/custom.conf
Then change the line:
#WaylandEnable=false
to
WaylandEnable=false
Press Ctrl+O and then Ctrl+X and reboot. If you don't wish to reboot you can do
sudo systemctl restart gdm
Which will restart your windows session (this assumes ssh into the box to fix as above).
I had the exact same problem. I somehow fixed it but I have the same screen as in your screenshot after restarting.
I did the following:
- Booted Ubuntu in recovery mode. (Long press Left Shift to show the menu while OS is booting).
- Then I have selected to "Repair broken packages"
- Then I have selected "Update grub bootloader
- Finally, "Resume normal boot"
Edit: I have installed "LightDM" and the problem is gone. Looks like there was an issue with "GDM3".
Voila! I have the login screen displayed was able to login. But restarting brings the problem back to square one. Could it be a problem related to Display/Graphic settings?
