Stuck in VT3 Ubuntu 18

When my system froze, I used Ctrl + Alt + F3 to enter Virtual terminal. Then I logged in and shutdown my system. Now when the system boots, it opens into a black screen (no text). I guess it is stuck in that VT. I am able to connect to this system via ssh from other system. How to exit from VT ? Tried Ctrl + alt + F7/F8 etc..
