libgdx can't start desktop project on ubuntu

Question

so, I just created libgdx project for desktop and imported it (gradle) to eclipse. When I launch it this error pops up:

Exception in thread "LWJGL Application" java.lang.ExceptionInInitializerError
at com.badlogic.gdx.backends.lwjgl.LwjglGraphics.setVSync(LwjglGraphics.java:446)
at com.badlogic.gdx.backends.lwjgl.LwjglApplication$1.run(LwjglApplication.java:118)

AL lib: (EE) alc_cleanup: 1 device not closed

I can't figure out what's happening. Project's created for android and launched in android studio working properly.

You need to install the xorg-xrandr package, see
