NVIDIA Continues Prepping The Linux Desktop Stack For HDR Display Support
Alex Goins of the NVIDIA Linux team presented on their HDR ambitions for the Linux desktop and the work they are still doing for prepping the X.Org stack for dealing with these next-generation computer displays. This is a project they have also been looking at for more than one year: NVIDIA Is Working Towards HDR Display Support For Linux, But The Desktop Isn't Ready.
One of their main contributions in this area is currently preparing the DeepColor X extension that is still being refined in collaboration with upstream developers.
Embedded below is the NVIDIA XDC2017 presentation on the HDR support (starts around 4:15 if the video embed is acting up).
NVIDIA isn't the only Linux stakeholder working on HDR support but Red Hat is working on it too. In fact, yesterday Red Hat's Adam Jackson sent in a OpenGL registry pull request for adding a GLX_EXT_no_config_context for porting the similar EGL extension to GLX for HDR use-cases.
