GUI showing only cursor on black screen

Hello, I'm fairly new to the Linux scene and having an issue where after trying to install Teamviewer on RHEL7 Workstation, I'm now left with a mouse cursor on a black background and no login method (via GUI). I can log in fine and SSH into it normally using command line, but I need to access it via GUI. The reason I tried installing Teamviewer was because I wasn't having much luck with any VNC product.
I've since removed Teamviewer but the issue remains. Any help is appreciated.
