"gdm" won't start automatically after updating to 40.0+

[Hanzel]

Hi and welcome to the forum

You might have this issue:

[Stable Update] 2021-04-18 - Kernels, Mesa, Wine, Plasma5, KDE Frameworks, LibreOffice, Bluez

For those having issues with GDM: If you want to use plymouth: install gdm-plymouth and libgdm-plymouth requires splash kernel flag If you want to use bootsplash-systemd or don’t want any boot logo at all: install gdm and libgdm and remove plymouth remove splash kernel flag

if not please read this on how to provide more info and how to format the output.

The output of systemctl status gdm and the above post should point you in the right direction.
