I have a notebook ASUS ZenBook UM325SA KG076T with an AMD graphics card Renoir/Cezanne.
Since upgrading to gdm3 42.0-1ubuntu4, gdm no longer starts at all. All you see is a blinking cursor.
The file /var/lib/gdm3/.local/share/xorg/Xorg.0.log contains the following:
xf86OpenConsole: VT_ACTIVATE failed: Operation not permitted.
xf86CloseConsole: KDSETMODE failed: Operation not permitted
xf86CloseConsole: VT_SETMODE failed: Operation not permitted

Edit: deleting or renaming the file /lib/udev/rules.d/61-gdm.rules was the solution for me.
