Is that the output in he Ubuntu system with the issue?

Is Ubuntu installed in a Virtualbox setup?

Yes, I have PC with windows 10 and ubuntu 19.04 on virtualbiox

Seems you are using a high res in the virtual system as indicated by the asterisk. Did you install the guest additions?

I don't think so, I don't know what is this.

see https://www.virtualbox.org/manual/ch04.html
installing is described below heading 4.2.1.1.
