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.

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.
