The Opti Got Its Cinnamon

Ok, the quest for getting Linux Mint across the board goes on...
Today installed Linux Mint 18 (Cinnamon) from scratch on the Optiplex.
No major problems, except that I had to connect a regular monitor to make the actual install, using the Apple Cinema Display -with the ADC adapter- was a no go...
I simply got no video... But, after making the install, connected the Apple monitor, booted, and everything was kosher.
Moving on...
Now restoring backups, installing and configuring stuff, what a major drag...
