On a new installation on a Lenowo w540 I configured
            bluetooth to use a mouse and it worked.  Then at a later
            stage (after installing many packages) it stopped working.
          
          
          I have read a lot on the internet about similar issues
            but could not find a solution yet.  I will appreciate some
            help from this list please.

Because
                experiencing your loyal love is better than life itself,
                
                my lips will praise you.  (Psalm 63:3)
