The issue is lightdm, something is probably misconfigured but I dont have the time to track it down right now Swap it for another display manager like gdm3 and it works I spoke too soon, as soon as I logged in there was no display again Seeing as how gdm worked, i decided to go down the gnome rabbit hole gdm3+ gnome desktop environment works, no other DE or DM worked

I found this post when looking for the video decoder hardware in the RK3399 The mali is a gpu, it does 3d rendering. So unless you are using something like openGL, the mali isn't going to do anything. It does not do the encode/decode of codec. There is another part in the SOC called a vpu Video Proccessing Unit -that does that. I know it's difficult to seperate them in the mind because most gpu cards have a encode/decode chip on them and we refer to the entire piece as a gpu but gpus and vpus are seperate
