In my case, when the LibreOffice lockup happened, the PC was still alive.
The Desktop/GUI is frozen, and the only thing still working is the mouse
which still follows the mouse movement.  However, you can only move the
mouse pointer,
but clicking on the mouse button doesn't work.

Keyboard seems to die, but Ctrl-Alt-F2 still works.  So I can use text mode
to kill the Desktop session (mate-session, gdm-session) to logout, then the
system will back
and GUI login dialog show up.

I can't repeat the problem, but it happens sometime (at CentOS 6x, 7x & 8x).
