Firefox: no hardware acceleration on nvidia

[k-jah-west]

Hi. I’m trying to enable HW acceleration on my latest Tumbleweed Plasma, but to no avail.

I’ve installed Nvidia drivers from opensuse’s repo by following the according guide on the opensuse wiki, Nvidia is working properly

as confirmed here by nvidia-smi

I then proceeded by installing codecs by opi, which always worked as a dream.

Then I followed this Firefox wiki of how to enable HW accel, however I can’t for the love of god enable it, and when I go on about:support, my table under hardware decoding says Unsupported (all in red for the second column), as shown on this pic:

My Firefox version is from opensuse’s repo, and not a flatpak version. One important thing to note is that HW accel worked on Debian Trixie on this same computer.

How do I properly enable my firefox for HW accel to work on openSUSE TW?

Anyone please?

Most likely that you are missing:

• libva-nvidia-driver

you also need in firefox:

• media.hardware-video-decoding.force-enabled → true
• gfx.x11-egl.force-enabled → true
• widget.dmabuf.force-enabled → true

Here’s mine:

That did the trick, thanks. I installed that package by opi from obs (X11:Xorg), because I couldn’t find it in the normal repos.

I wish someone more knowledgeable than me would update that Firefox wiki article cause it seems its outdated then.

Thanks again
