I do not have nvidia drivers installed (‘un’ means uninstalled status), Yes I have a minimum GUI install because I run a RDP daemon on the box allowing me to do remote desktops from Windows. And yes, I have had this working with the corrupted video using an older version of the Plex server, but for some reason the newest version of the Plex server seg faults even though others have reported it works!
