Rebooted Centos7 machine, and can only log in to Root

[morph436]

Hello Everyone,

I was using remote desktop to my CentOS 7 machine and while I was on site I was using Firefox.
I tried to open it in the RDP session but it said it was already running.
So I killed the process, but it kept repeating that it was still open and suggested rebooting if killing the process didn't work.

So I rebooted, but now, even locally I can't log back in using my username. I'm trying to log into the GUI. If I select "select a different user" and use the "root" user, I can log in.
If I do ctrl+alt+F2 to get to the TTY login, I can use the other user and log in just fine.

When I try to log in to the GUI with this user, it says I had previously logged in before, but then almost looks like it bootstraps, or cycles and puts me back to the login page again without errors.

Any suggestions or outputs I can provide that may help troubleshoot this issue?

I'm pretty new to CentOS, so please forgive my ignorance. And thank you for your help.

This is a firefox design thing. When run on a remote system like this, it checks your *running* system and tells you that it's already running. You have to invoke it on the remote end with `firefox --noremote` (might be --no-remote).

For the rest of it, since you can login as root, go read all your log files under /var/log and see if anything shows up there.
