Long story short, I've deleted lightdm because of the error:

“Failed to start light display manager.”

After I reinstalled it with synaptic. How to get it (or smth else) back?

What and why I have done:

Installed today fresh new linux mint cinnamon 19.3. Had a problem that after log in there was no desktop, only mouse cursor. So I rebooted the system, opened the console in the login screen (ctrl-alt-f1) and typed startx. Desktop appeared, but I was not satisfied that I have to manually start it. So I found "solution", that said to use synaptic and reinstall lightdm. I did that and then I got stuck on the logo/loading screen with error:

“Failed to start light display manager.”

I've rebooted to recovery mode, opened root console and deleted lightdm with sudo apt remove lightdm, then started the network manager and upgraded all packages.

After reboot there was no login screen, only console with:

“Enter your login.”

Well, I logged in to my account and typed startx. Everything works out, but now I dont have login screen at all.

Tried to install lightdm with synaptic but got stuck on logo/loading screen once again...

The question, is there any way to install new or old login screen, so I dont have to manually type my login and startx command?

  • It seems that this is a compound problem. If you just installed Linux mint cinnamon, try a reinstall and with the first problem you get, seek help. If you don't want to do that, I'd say be content logging in through terminal and running startx.

  • Hmmm, why don't you try a different version of Linux then? I'm familiar with Debian, and it works like a charm.

  • Because I've already installed Mint and I'm too lazy to reinstall the system once again

  • Ok, here's a possible solution. Try sudo systemctl set-default graphical.target That should launch the GUI login when you boot.

I've installed another distro because I didnt found any solution for mint.

Never mind! There is the solution! Here's what worked for me:

So,

  1. delete all nvidia drivers, then
  2. reboot with nomodest instead quite splash grub boot flag
  3. log in, and install nvidia drives 430.5 via driver manager, reboot.

And that's all. System was reinstalled without any additional software, probably it could led to the successful fix, idk.

  1. remove drivers

    sudo apt purge *nvidia*; sudo apt autoremove; sudo apt remove nvidia-*; reboot;

  2. hit e while in grub menu: change 'quite splash' to 'nomodeset'

  3. boot, log in, install drivers.
