Running without X? #5483

Closed lucasmr closed 7 years ago

lucasmr commented 7 years ago

[Description of the bug]

Trying to run retroarch without X installed on a gentoo machine. The relevant user flag "kms: Enable KMS context support (for OpenGL-based execution from a virtual terminal outside of a display server)" hints that this might be possible. All USE flags are below:

Nevermind. RADEON_FB was enabled on the kernel, which blocked DRM KMS from being available. Removing kernel framebuffer fixed.
