My Father (who died last year at the age of 86 having had a damn good innings) ran a computer with Xubuntu Linux on it that I had installed for about 14 years.
He lived in England and I live in Bulgaria; so I got quite a dab hand at running up "pictorial guides" to all sorts of little problems and questions he had.
If anyone 'out there' needs the same sort of help please feel free to contact me outwith this forum via e-mail and I will do my best.
This is a very expensive service: charge is one "Thank you" per item. I am happy to offer this as a sort of memorial to my father.
