Linux KMS Mode

Linux KMS Mode


KMS (Kernel Mode Setting) mode is a feature where RetroArch can use the OpenGL driver outside Xorg, running straight in the virtual terminal. It is a fairly obscure feature, but very powerful in a console scenario.


To use KMS mode you need:

  •      Recent version of MESA (9.0+) (dev)
  •      libgbm 9.0+, libdrm (dev)
  •      Open source driver which supports KMS
  •      ./configure with flags "--enable-kms" and "--enable-egl"

These require a fairly up-to-date distro.

After compiling RetroArch, you should see this when running retroarch --features:

     KMS / EGL context support: yes

If KMS mode is working correctly, RetroArch should start up outside Xorg as well.
