Linux mint freezes after exiting tty

I have this awkward bug, where Linux totally freezes, black screen and nothing works except forcing shutdown then restart again What i have: Linux mint 19.1 with i3wm Steps to reproduce: startx from tty1 switch to tty2 log in the type “exit” Everything will freeze, and if u switch to tty1 it will give u black screen I find this really weird and awkward, can someone give u a solution for this ?
