OS: Ubuntu 16.04. UE4: 4.16, 4.17, 4.18
I have tried to install three version of the engine with PC, Laptop and Server. All have the same problem which I can’t type anything inside the Editor; however, when I click on something and I hit backspace it can delete it! just cannot input anything.
I followed Building on Linux wiki link by first install ubuntu dependencies and then proceeded with first time setup.
