@claudiom Yeah! It was 10.2. I upgraded to 12.0 and it crapped! But it was a nice system. Sadly, I assumed I needed to reinstall everything so I declined using it anymore. Perhaps too much upgrade at once.
@peron Yeah, I had some problems upgrading an old server from 11.x to 12.0, something to do with the bootloader and the RAID controller on the server. After about a year or two, I tried again and it worked this time.
@peron Probably not 12.3 since 12.1 is the latest. 😁 It runs well! On this desktop system, I have a NVIDIA Quadro FX 570. It works so long as I have the proprietary NVIDIA drivers installed. I normally wouldn't use NVIDIA (Team AMD here), but that's what this system at work has, so I'm using it.
