Comment 5 for bug 1970389

I'm experiencing similar issues, but I'm unable to switch desktop manager to Xorg as I don't have such option on login screen. I have tried to switch the session type to XOrg by modifying /etc/gdm3/custom.conf and setting WaylandEnable=false as suggested on several websites.
However, when restarting gdm3 or the system, this leads to system hanging and displaying a white cursor (underline) on black screen without any response to keyboard input. I have then to go to recovery mode, login as root and modify the file back to use Wayland...
