The upcoming Blender 5.0 3D modeling software application is introducing High Dynamic Range (HDR) display support on Linux when making use of Wayland — no X11 support for HDR — and Vulkan graphics accelerator.
HDR support for Blender 5.0 on Linux is currently considered experimental. Enabling the HDR support on Linux for the Blender creator software requires having a High Dynamic Range display (of course) and be running on a Wayland desktop, enabling Vulkan API acceleration rather than OpenGL, and enabling the feature currently deemed experimental.
As the Blender HDR support on Linux has been tested with a limited number of configurations so far, it’s currently being treated as experimental. Depending upon testing feedback it may be promoted beyond being an “experiment” feature or Blender 5.0, so we’ll see. In my testing of the latest Blender 5.0 alpha build on Ubuntu Linux with Samsung Odyssey OLED G8 G81SF and ASUS ROG Swift OLED PG27UCDM displays, this experimental feature was working out fine in my basic tests.
More details on this initial HDR support for Blender 5.0 on Linux with Vulkan/Wayland can see this Blender DevTalk thread for all the details and to share your feedback on any testing.
