New to the forum and to Linux, so please forgive me if I seem naive as I am. Officially made the switch to Linux this week and I’m enjoying it immensely, however there are a couple hiccups that I can’t seem to find the answer to online. My system is running a Ryzen 5 2400g and up until about a month ago I was using the integrated Vega 11 graphics while I was saving up for a dedicated graphics card. I finally got my AMD Radeon RX 590 Fatboy and the switch from my integrated graphics to the dedicated was nearly seamless on windows. Just updated the graphics drivers and it worked. On Linux was a different story.
I’m currently running Zorin OS 15, and have updated my kernel to 5.1.15 as I know the AMD Open source drivers are pretty good. The problem that i’ve found is while my system is detecting the 590 as the graphics cards, but in gaming tests such as DOOM (2016) using Steam Play, Deus Ex Machina natively in steam, and Overwatch using Lutris I’m getting gaming results similar to how the integrated graphics performed. Another problem I’ve found is that the HDMI port on my motherboard is the only display port that isn’t a black screen. The ports from the dedicated card produce no image.
Is there something I need to update in the drivers or something that I need to configure that I haven’t yet? My os is nearly stock at the moment except for the kernal update. Any help would be greatly appreciated.
