Phoronix: New GNOME Code Speeds Up Performance For NVIDIA Proprietary Driver Multi-Monitor

A newly-opened merge request for GNOME's Mutter compositor adds hardware acceleration for the NVIDIA proprietary driver for secondary GPUs such as in the case of hybrid systems and other setups with multiple monitors whereby the NVIDIA GPU with proprietary driver is powering some of those outputs...

BTW: I have the exact same problem and experience with KDE and KWIN on me Lenovo ThinkPad P52 laptop. It's one of the few reasons why I'm still using X11 instead of Wayland.

Wouldn't the usage of GL_OES_EGL_image_external decrease performance in primary NVIDIA GPU configurations?

Oh, so that's why it was so slow on my laptop. Ok, now I can see for the first time a reason big enough to claim Wayland is not yet ready for all users.

I wonder why Gnome is so eager to solve all problems for Nvidia.
Does Nvidia at least pay them?

Daniel van Vugt at Canonical who leads much of their upstream GNOME improvements/optimizations has worked out a prototype of hardware-accelerated GPU-to-GPU copies for NVIDIA outputs under Mutter Wayland session

Here's the relevent KDE bug. it looks like kde 6 will include a fix for it.

I was able to get it to work well using the all-ways-egpu script using method 2 and 3

Though I did run into other issues with the screen distortion / draw area. the second monitor would basically not have a background for parts of the display that were different between monitor 1 and monitor 2 and would redraw whatever was over that section over and over unless a live window covered it up.. i don't know where the bug for this one is tho as it's a hard description to make.

GNOME (and other projects) should stop fixing and working around the pile of fucking shit that NVIDIA's closed source software is in the environment of OSS Linux, they are supporting a multibillion Dollar company, that could not give a lesser f` bout them.
