Computer Freezes on login screen

[gtribe5]

Running a centos 6.10 computer. Recently the root partition was out of space, the user was able to free up space but now when the computer starts it freezes on the login screen with the list of usernames. The mouse and keyboard are unresponsive. We can SSH into the computer.

Since you can ssh in, start by reading the various logs in /var/log like messages, secure and Xorg.*.log looking for clues.
