UbuntuMate 16.04 and QT5

I have installed UbuntuMate 16.04.5 as virtual machine in VMware, Mate version is 1.12.
After successful installation of UbuntuMate as Virtual machine, i installed VMware tools also.

Now after installing “qt5-default” package from repositories using “sudo apt install qt5-default”, when system reboots, i dont get the login screen. It remains blank screen with cursor also still.

if its not some bug, then i think i am missing some step. I have done same thing with Ubuntu 16.04 without issues.
Any idea what may be wrong here?
