Offloading && Chrome?

Graphics / Linux Linux
1

Hi,

I’m currently on Nvidia 525.85.05 and Linux 6.1.10.

In an offload set up, I can get apps (e.g. Google Earth, Zoom) to use my dGPU. However, my browser (Brave) refuses - more below. In searching the forum and web searches, it seems I am not the only one.

Using brave://gpu/ confirms that acceleration is not available when I attempt to use the Nvidia environment variables (see below). At startup, the Brave issues errors (also below) - I did some web searching on the warnings but no luck.

Is the Chrome engine still not able to handle offloading? Is this a a Brave issue? If so, I can report it to them.

Thank you for any help!

This once worked (apart from video hw accel) but is now broken in chrome (since v94, AFAIK). Funny enough, I just tried and it worked…once. On subsequent runs, it wouldn’t work again. Don’t really know but I’d rather suspect a bug in chrome.

Hi,

Thank you for trying and replying with the results. Very bizarre non-deterministic behavior! :)

I have confirmed that the latest Brave and Google Chrome drops fail:

Google Chrome - Version 110.0.5481.96 (Official Build) (64-bit)
Brave - Version 1.48.158 Chromium: 110.0.5481.77 (Official Build) (64-bit)

Later today I’ll test with a beta version of both. I’ll post the results. If they fail, I’ll report an upstream bug and post the link too.

Hi @generix,

I got it to work. I believe there still is a defect: It only works from a boot and only if I do not re-login.

When you get a chance, please try the following with an Optimus environment set up:

  • Reboot

  • Confirm only one GPU provider listed:

    xrandr --listproviders | grep '^Provider [0-9]' | cut -d: -f1

  • Monitor dGPU:

    watch -n1 nvidia-smi

  • Start brave (or a chromium based browser):

    __NV_PRIME_RENDER_OFFLOAD=1 __GLX_VENDOR_LIBRARY_NAME="nvidia" brave-browser-stable

  • Confirm via the nvidia-smi that dGPU is being used.

  • Confirm hardware acceleration via brave://gpu- or equivalent.

Thx a lot!

I don’t understand this, this would mean render offload is broken.

7

In this case I believe broken is on a spectrum. I see occasional, odd browser repaint flashes.

Using nvidia-smi as the source of truth along with brave://gpu, acceleration is enabled.

Here’s an example showing nvidia-smi with my current browser offloaded: https://i.imgur.com/S8RpeLK.png

Update

If possible, please try the test as I think it might be fruitful in determining where lies the issue.

On my end, after several hours of constant browser use, there are definitely, somewhat random, redraw issues.

As for now, you can offload with vulkan:

__NV_PRIME_RENDER_OFFLOAD=1 __VK_LAYER_NV_optimus=NVIDIA_only /usr/bin/microsoft-edge-stable  --ozone-platform-hint=auto --enable-zero-copy --disable-features=UseChromeOSDirectVideoDecoder --enable-features=VaapiVideoDecoder,VaapiVideoEncoder,Vulkan --use-vulkan --use-angle=vulkan

Vulkan as angle backend is a must. But this causes some input lag as I see, still this is the best I can achieve on a optimus laptop after two days of trial and error.

Thank you so much!

I’m definitely seeing my Nvidia widget displaying action.

On the input lag, I’m assuming this is when you’re typing in text fields eh?

Just moving mouse can cause it occasionally, but not always. I use reverse prime, someone on the forum complain about this, so I guess it’s not a chromium related problem.
