Public bug reported: Hi all,
after upgrading from bionic to focal I switched from lightdm to gdm3 to use Gnome Desktop. Gdm3 crashes systematically when enabled as default display-manager with a blank display with the following message: Oh no! Something has gone wrong. A problem has occurred and the system can't recover. Please contact a system administrator. In /etc/gdm3/custom.conf I've tried the following settings: WaylandEnable=false -> crash WaylandEnable=true -> crash I've enabled Debug but I cannot find any correlation with the error message. Gdm version 3.34.1-1ubuntu1. Switching to another display manager like lightdm or sddm solves the problem. I've a Dell Inspiron with Intel U620 graphic card. The problems happens with the laptop display alone but also with external monitor connected via HDMI. Thanks in advance for your help.
