Unable to print plots and images

I am using Matlab 2017b on Ubuntu. It's two days that I cannot plot anything and I receive only error messages. When I open Matlab there is the following red message:

com.jogamp.opengl.GLException: X11GLXDrawableFactory - Could not initialize shared resources for X11GraphicsDevice[type .x11, connection :0, unitID 0, handle 0x0, owner false, ResourceToolkitLock[obj 0x429a8af3, isOwner false, 28453244[count 0, qsz 0, owner NULL]]] at jogamp.opengl.x11.glx.X11GLXDrawableFactory$SharedResourceImplementation.createSharedResource(X11GLXDrawableFactory.java:326) at jogamp.opengl.SharedResourceRunner.run(SharedResourceRunner.java:297) at java.lang.Thread.run(Thread.java:745) Caused by: java.lang.NullPointerException at jogamp.opengl.GLContextImpl.makeCurrent(GLContextImpl.java:688) at jogamp.opengl.GLContextImpl.makeCurrent(GLContextImpl.java:580) at jogamp.opengl.x11.glx.X11GLXDrawableFactory$SharedResourceImplementation.createSharedResource(X11GLXDrawableFactory.java:297) ... 2 more Exception in thread "Startup Class Loader" java.lang.InternalError: XXX0 profile[1]: GL3bc -> profileImpl GL4bc !!! not mapped at com.jogamp.opengl.GLProfile.computeProfileMap(GLProfile.java:2047) at com.jogamp.opengl.GLProfile.initProfilesForDeviceCritical(GLProfile.java:1917) at com.jogamp.opengl.GLProfile.initProfilesForDevice(GLProfile.java:1866) at com.jogamp.opengl.GLProfile.initProfilesForDefaultDevices(GLProfile.java:1835) at com.jogamp.opengl.GLProfile.access$000(GLProfile.java:79) at com.jogamp.opengl.GLProfile$1.run(GLProfile.java:229) at java.security.AccessController.doPrivileged(Native Method) at com.jogamp.opengl.GLProfile.initSingleton(GLProfile.java:215) at com.mathworks.hg.peer.JavaSceneServerPeer.initializeJOGL(JavaSceneServerPeer.java:149) at com.mathworks.hg.peer.JavaSceneServerPeer.<clinit>(JavaSceneServerPeer.java:119) at java.lang.Class.forName0(Native Method) at java.lang.Class.forName(Class.java:264) at com.mathworks.mde.desk.StartupClassLoader.loadClass(StartupClassLoader.java:262) at com.mathworks.mde.desk.StartupClassLoader.access$900(StartupClassLoader.java:25) at com.mathworks.mde.desk.StartupClassLoader$2.run(StartupClassLoader.java:248) at java.lang.Thread.run(Thread.java:745)

and if I try to plot something this is what happen:

>> a=[1,2,3,4]

a =

     1     2     3     4

>> b=[5,7,9,11]

b =

     5     7     9    11

>> plot(a,b) Caught unexpected fl::except::IInternalException >>

What can I do? Thank you very much for your help, Kind regards,

Federico

This is the red message with right indentation:
