Login password issues

Good evening

i recently installed Ubuntu Mate 14.04 and I am facing log in issues.
Specifically when I am booting my laptop there is no log in screen
requesting for a password. Searching around I was unable to find a
solution as many related topics weren’t using mate’s environment.
Any thoughts?

You can still login through the console?

You could try installing or reinstalling lightdm.
sudo apt install lightdm

you can also check to make sure you are using lightdm as you display manager

  $ cat /etc/X11/default-display-manage
  /usr/sbin/lightdm

Many people are running Mate 14.04. However this is not an official release of Ubuntu Mate. 14.04 came out before Mate joined the Ubuntu flavors. Since this is a new install I would recommend a reinstall using Ubuntu Mate 15.10.

About your current problem. Did you set it right during the install?

Looking around I also came across this:

It may happen that your system boots so fast that LightDM service is started before your graphics drivers are properly loaded.

Running a SSD by chance?

Dear mparm920,
I can log in through console and graphic environment as well. The think is that I am not asked to use a password before I get access to my desktop.
However, I used

and terminal reported that "lightdm is already the newest version."
Using

Terminal reported:"No such file or directory"

Dear v3xx,
re-installing Mate is not a solution for me as I am running on dual boot
booth windows and Mate and I would have to set up the whole system
again.
As about the installation process honestly I don't remember, and also I
am not running an ssd hard drive.

However, today I made a second user protected with password as well.
When I reboot my system I noticed that mate logged in my primary user
without asking me to use a log in password or to choose a user account.
Any ideas?

Thanks for your time.

What about user settings?

System>Administration>User and Groups

And just set yourself to be asked to login.

This is how it looks from the beginning.
Further more i noticed that if i disconnect from my user account system asks for a password to login in again.There must be a problem on the booting process.I don’t know if this could help…

try to a available tty
sudo apt-get purge lightdm
reboot (this process just make sur the lightdm process is not in a ghost state somewhere)
go back into you tty
sudo apt-get install lightdm

this should reconfigure all things just fine.
If this is now loading good i would suggest you to pastebin your /var/log/lightdm/lightdm.log or even your syslog could be usefull

I did what you told me about lightdm.
I also pastebin my /var/log/lightdm/lightdm.log
and syslog as you suggested.
