As per aplattner’s suggestion from https://devtalk.nvidia.com/default/topic/957814/linux/prime-and-prime-synchronization/post/4953175/#4953175 , I’ve taken the liberty to open a new thread for discussing on PRIME GPU render offload feature on Optimus-based hardware. As you may know, Nvidia’s current …

I’ve been dealing (giving that term a super-wide berth) for literally over 10 years now under Linux, and my latest (this past weekend) attempts at configuring two GeForce GTX 1080 cards in SLI mode with a hardware bridge that was included with the motherboard I purchased has proven to be the most f…

This week Kyle pushed a new GLX extension to make possible the PRIME offloading. [url] Sign in · GitLab Do NVidia have any expecting release plan for this support, since everithing in Xorg seems to be implemented now (just waiting feedback/merging)?

Looks like Kyle’s code is now in the master branch. So I guess now we wait for an NVIDIA driver update to take advantage of it?

Good news! [image] Linux, Solaris, and FreeBSD driver 435.17 [beta release] Release highlights since 430.40: Fixed a bug which caused the kernel to panic when exiting a single X server when multiple X servers were active and in an SLI configuration. Fixed a regression introduced…

Just tested this and works flawless so far even with Steam Proton. When nvidia-drm.modeset=1 is set, the nvidia gpu also has to be set up in xorg.conf, otherwise the modesetting driver grabs the nvidia device, e.g. Section "ServerLayout" Identifier "layout" Screen 0 "iGPU" Option "AllowNVIDIA…

I think a small script that turns on/off the NVidia card with bbswitch and starts the command with prime offloading could be the answer.

bbswitch can only turn off the nvidia gpu when the nvidia driver is unloaded which can’t be done because it’s used by the Xserver.

What is the status of HDMI output with this new driver?

Good news!

Is there any chance this could get backported to nvidia-390xx?
