I've been tweaking with my system appearance lately, and wanted to change Gnome's Display manager and change the login screen theme.
After boot, the display shows the following for few seconds:
/dev/sda5: clean, 754129/10690560 files, 13222358/42732800
Started bpfilter

muath@muathasus:~$
Pressing ctrl-alt-f1
or ctrl-alt-f7
have no effect.
I could continue to desktop manually by writing startx
or by sudo service start gdm3
.
I have Ubuntu 19.04 with X.org drivers, and haven't upgraded lately. Also tried to switch from gdm3 to lightdm or to slim, with no effect.
Additional:
Output of systemctl status gdm.service
include:

Trying to change gnome's display manager using sudo dpkg-reconfigure gdm3
