Android Studio AVD error launching

Question

I have a Nexus 6P API23 emulator downloaded on my Ubuntu 15.10 PC. When I try to launch it, it fails and a dialog box pops up and says:

(AVD config: Nexus 6P API 23 x86 -- Hardware-GLES 2.0 Graphics)

Cannot launch AVD in emulator.
Output:

I have tried other AVDs and they don't work.

you can also use "Software" in the Emulated Performance Graphics option, in the AVD settings
