Let’s gather data and info about the feature introduced with the 450 driver. Starting to fill with questions Q: Does this work with PRIME synchronisation? Q: Does this work with Render Offload? Q: Does this work with D3/runtime power management? Feel free to share your adventures and failures d…

It seems like the xorg issue responsible for fixing the display lag has ended up stalling. ( Sync present to slave outputs (!460) · Merge requests · xorg / xserver · GitLab ) Since this is the most pressing issue for Reverse Prime support on Nvidia, does anyone have any idea (or can poke them) on a s…

xorg is pretty much now unmaintained and that issue is highly unlikely to be solved now. Nvidia is deep in work to make their driver and Optimus based laptops work with Wayland + XWayland correctly (to the benefit of everyone).

@agoins What is the status on internal bug number 2759189 for Reverse PRIME to work with amdgpu? Also, @SenojEkul can you share the discord link that you have mentioned earlier in the thread.

I’m curious how the D3 power management on AMD platforms is coming? I have a 2020 Asus G14 with 4800hs and 1660ti gpu. Using Fedora 33, the dgpu will not enter d3cold, and remains on at all times unless explicitly not loaded (using igpu only). I’ve noticed people with 2021 models reporting that t…

@Syzygianinfern0 470.42.01 Beta just launched with support for Reverse PRIME with AMDGPU. It also supports Reverse PRIME/PRIME Display Offload where both GPUs are NVIDIA. For the new support to work, the nvidia-drm kernel module has to be loaded with modeset=1.

So @agoins does this driver support optimus laptop setups with intel integrated GPU and nvidia discrete GPU in wayland?

@jcstryker I’m using Dell G5 5590 with RTX 2060 + Ubuntu 21.04 (Wayland) and I wonder the same question.

From my testing, attempting to connect an external display while Wayland is the primary display manager will completely hang the computer. I’m not entirely sure how to get logs or information for this.

I have the same issue on a dGPU routed DisplayPort monitor. I have run the bug report, which would probably be similar to yours. When using Xorg, I get errors trying to set the resolution. Hopefully they can fix this. data (931.7 KB)

For anyone who still trying to make it Ubuntu + Wayland. I did the hard work of trying to figure out how to get this done over Wayland + NVIDIA 470.42.01: after you made all the necessary steps to meet the NVIDIA requirements and updated everything then you need to recompile your kernel. after…

Intel+NVIDIA Reverse PRIME works on 510.60.02 driver with 5.17.5 kernel, but Xorg crashes when modifying the external display options (like, changing the resolution or turning it off).

Some details are mentioned here: nvidia: Add Reverse Prime Sync by GoogleBot42 · Pull Request #165188 · NixOS/nixpkgs · GitHub
