I have just installed Ubuntu 14.04 for the first time boot. I am a long time MS Windows user and don't like where Windows is headed so I decided to switch to Ubuntu and only use Windows for gaming.
However. I cannot get into my computer after the lock screen appears. It says the invalid password message no matter what password I use.
I have googled for a little bit, and the closest thing on here I could find is:
Password is incorrect – when tried to login into Ubuntu 13.04 [duplicate]
. Though there is no answer there.
I should note, that I mistakenly as a Linux newbie:
- Did
chown -R david /etc
and lost thesudo
power. - then I booted into recovery mode and ran a few things and ran
chown -R root:root /etc
and that fixed thesudo
problem. But I think when I did that the lock screen stopped working and I can't get into the computer. I have to restart and have it auto login.
I went through the first 10 suggestions when posting this and nothing close helped.

I had this exact issue. The password worked in terminal, but not in LightDM. I could login as other users, just not the one I wanted. I even changed the password from a different user and also in recovery mode. LightDM didn't give a password incorrect notice, there was just a graphical glitch.
I don't have a fix for LightDM, but this works for me as a work-around, I set GDM as default display manager - GDM is not having any login issues:
Install GDM.
It will ask you which display manager to set it as Default, select GDM.
If it is already installed. Run reconfigure.
