Install default lightdm on debian 9 gnome [SOLVED]

Postby Scorpion » 2018-11-16 09:50

I updated the kernel with:
Code: Select all
apt install linux-image-4.18.0-0.bpo.1-amd64
in the loading messages it states Failed to load kernel modules and then nothing happened.
I removed the update kernel.
After I discovered that somehow lightdm was removed. So I reinstalled it.
How can I restore the default lightdm? I can' t lock the screen.
If I reinstalled the update kernel and after lightdm I will be able to use it?
Thanks

Install lightdm and run as root (or super user)
Code: Select all
dpkg-reconfigure lightdm

I tried that but it doesn't restore the "debian lightdm". Nothing has changed.
I can' t lock the screen. I used to press super+L that is still the lock screen shortcut.
Are
Code: Select all
/usr/share/lightdm/lightdm.conf.d/01_debian.conf
/usr/share/lightdm/lightdm-gtk-greeter.conf.d/01_debian.conf

the only files that change lightdm ?
If restore those 2 files will I have the "default debian lightdm"?

GDM is a better choice for Debian anyway because it allows X to run as a non-root user, unlike LightDM.

I think so, I can lock the screen and it is the gnome display manager.
Since gdm3 failed to start when I updated the kernel, I thought was lightdm the default dislplay manager and that it got removed somehow.
