Hi there!
I’m using SDL2 2.0.16 on a RPi 4 (CM4) in a buildroot (not RaspberryPi OS) with and my app is using OpenGLES and kmsdrm (without X), and SDL_GetNumVideoDisplays();
always returns 1, where the CM4 has 2 HDMI ports.
HDMI0 shows my app and that works great, but HDMI1 always shows the linux console FB.
Is there a way I can use the second port, either in an extended mode
or by a second process?
I’m probably doing something basically wrong, I’m very much a SDL and GL novice and working of a modified version of the Dear ImGui SDL2 backend.
Any help or pointers would be appreciated.
Cheers,
