Ubuntu 16.04 - Genymotion: /dev/hw_random not found

Issue

I install Genymotion on the Ubuntu 16.04 64Bit. I created a virtual emulator for Android 6.0 then I run this emulator but emulator is disappearing and the emulator is running background. I checked the emulator on the VirtualBox and I saw this issue:

Solution

I solved the issue:
System Settings > Software & Updates > Additional Drivers : Then you click Apply Changes button and you restart your pc.

I don't know reason of the issue, open source driver is not running for Genymotion but NVIDIA is running.
