Hi Chris, Thank you for the reply. 1) It was 18.04 2) During the install process there is a reboot. It would often hang here, and sometimes after 5 minutes or so, it would reset itself. After initial installation, it would sometimes hang at the login screen, but 90% of the time would hang within 60 seconds of hitting the desktop. Pressing the "activities" keys button would load the icons for the programs. After clicking any program it would crash halfway through the animation to fade out the icons. 3) I had to look at the list again. Other than AMD or NVidia I wasn't under the impression there was a great amount of differentiation in the 7720. CPU and chipset does look the same. However, I believe this 7720 has a Quadro P4000 Mobile instead of the P3000. I appreciate your guys help. I can't stand leaving this equipment on Windows 10.
