I recently setup a beefier plex server with a gtx 1070 running on ubuntu (switching from junk old Mac). As a result of me moving from being a mac only user to an ubuntu machine it has not been easy for me and I probably messed something up. I was running on ubuntu 18 lts and hardware transcoding didnt work so I switched to 19.10 and it still didn’t. I read the forums and added Plex to video and render groups but it had no effect, please help.
