Ubuntu 16.04 - Genymotion: /dev/hw_random not found

Question

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:

Answer 1

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.

Answer 2

I had exactly the same issue as in the image but i am using Windows 10 and the version of Genymotion is 3.0.1, so the problem was that my graphics card no longer matches Genymotion requirements. So simple solution was that I had downgrade Genymotion to 2.12.2.
