-BUG Discrete graphics not detected/greyed out

So I decided to Install Lutris on a computer with discrete AMD graphics and an integrated IGPU, and noticed that the “switch to discrete graphics” was greyed out. Actually same computer had the feature working last year, with Arch and Gentoo, but in the older UI.

Checked the forums and saw a similar problem. The guy actually only had an IGPU, but I got an interesting piece of info: Lutirs uses lspci to detect the GPUS. I tried lspci and found that both cards are detected, but shows the format differently:

00:02.0 VGA compatible controller: Intel Corporation UHD Graphics 620 (Whiskey Lake) (rev 02)
3b:00.0 Display controller: Advanced Micro Devices, Inc. [AMD/ATI] Lexa XT [Radeon PRO WX 3100]

I can “Force” the setting by manually appending “DRI_PRIME=1” in the command prefix option, but still I think this is a bug in the way Lutris detects GPUS: Shouldn’t be greyed out!
