LOL, succeeded means something very different in this context than what you are implying. Linux did succeed on the desktop and in fact it has made many great strides that makes performance and desktop management better than Windows in almost every way. Just because it doesn't have majority marketshare, in part due to Microsoft making backroom deals to ship computers from the slave labor factories that Microsoft supports in order to sell $200 pieces of junk adware laptops at Walmart, doesn't mean that it hasn't been successful.
