Nvidia 450.51 driver brings many new features and bugfixes
Owners of laptops with their HDMI wired to Nvidia should be happy now as Reverse-Prime has been introduced in 450.51. Along with a quite long list of other goodies, changelog has the following:
- Added support for displays connected to NVIDIA GPUs to act as PRIME display offload sinks, also known as "Reverse PRIME". See the chapter titled "Offloading Graphics Display with RandR 1.4" in the README for additional information.
As of now it's possible to build and install this driver using AUR's
nvidia-beta-dkms PKGBUILD. I'm running it now but I can't test reverse Prime since my display is wired to Intel GPU.
