I have the xorg-x11-drv-amdgpu vulkan-tools mesa-vulkan-drivers installed.

I need to know what I need to do about this. Used to work before I reinstalled Fedora 38. (Because of the boot issue.)

I can run Diablo Immortal just fine on the Wine GE, I don't undertstand on why the BGFX loading is having an issue. MAME can run without the BGFX.

I tried this.

[mitchell@localhost-live mame]$ ./mame -videodriver amdgpu -video bgfx
Could not initialize SDL amdgpu not available

I don't understand. I did removed Nvidia.

echo 3971468 | sudo -S yum remove nvidia* xorg-x11-drv-nvidia* -y

Only found this. nvidia-gpu-firmware-20230515-150.fc38.noarch I took it off.

That's not what -videodriver does. It picks one of SDL's built-in render drivers, normally X11 or DirectFB.

Regarding your other error, at the login screen choose the X.org Session from the drop-down list of available sessions. On a stock Fedora install you'll have "GNOME Wayland session" and "GNOME X.org session" at least. See https://docs.fedoraproject.org/en-US/quick-docs/configuring-xorg-as-default-gnome-session/

ok I will try that.

Thank you R. Belmont. Works.

The issue is that bgfx does not work with wayland. The error is there to avoid a segfault which would happen otherwise. You do not have to switch the entire session to X11, but you need to pick -videodriver x11 if you want to run -video bgfx. Fedora carries a downstream patch which makes SDL use wayland by default:
https://src.fedoraproject.org/rpms/SDL2/blob/rawhide/f/SDL2-2.0.22-prefer-wayland.patch
Or you can use -video opengl with wayland.

Yeah I know. I made shortcut while back after he talk to me. I saw the link too.
