Dear Maintainer,

when I try to use the context menu with the right-click of the mouse or the
menu key on the keyboard, there are most of the time no results.

1. In the first use case, the context menu appears after the mouse click and it
is possible to select the various options:

a. After the click on copy, if I try to paste on some applications like gedit,
gnome-terminal or gnome-text-editor, mostly it does not work.

b. After the click on paste from other applications, like Firefox, gedit,
gnome-terminal or even other gnome-console windows, mostly it has no effect.

c. Select all does not select anything.

2. In the second use case, the menu keyboard does not open any menu.

The shortcuts <Ctrl+Shift+C> and <Ctrl+Shift+V> work usually without problems.

Unluckily I was not able to understand why in few situations copy-paste works
through the mouse or does not work with the keyboard shortcuts.

Thank you in advance,

Best Regards

Dear maintainers,

I finally found when the problem happens. The installation of the NVIDIA
proprietary drivers led to a automatical change to the X.org session as
default.

The bug appears only under the X Window System.

I hope it can help.

Thank you in advance,

Best Regards
