Hi:

I tested all the commands that you told me, but, I still have the error that I had specified to you:

"gonzalorojascosta@gonzalobrain:~$ freeview

This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem.

Available platform plugins are: eglfs, linuxfb, minimal, minimalegl, offscreen, vnc, wayland-egl, wayland, webgl, xcb.

Abortado (`core' generado)
gonzalorojascosta@gonzalobrain:~$"

Sincerely,
