Struggling to get NVIDIA hardware acceleration on Firefox

Hello all:

I got a new 1440p monitor in November, and ever since then my Arch install has felt very sluggish, especially in Firefox. It seems that I'm not getting hardware acceleration in Firefox anymore - I probably never was and didn't notice. Now I am because my i7-6700 CPU is struggling to do graphics at 1440p.

I have a GTX 1070. Hardware acceleration appears to work OK outside of Firefox.

I have installed nvidia, nvidia-utils, libva-nvidia-driver.

Despite the above Firefox about:support tells me I'm using WebRender (Software) and Hardware Decoding unsupported for all formats. I have 

media.ffmpeg.vaapi.enabled = true, gfx.webrender.all = true

in about:config. Nothing I do seems to enable hardware decoding in about:support.

Would love to solve this issue because my work relies on a speedy Firefox, and it's been running like crap since I got this monitor.

Thanks!

Re: Struggling to get NVIDIA hardware acceleration on Firefox

1. libva-nvidia-driver doesn't work out-of-the-box, it requires manual intervention. Did you follow the instructions from here?

2. How exactly do you verify that HW acceleration is working or not? Because checking about:support in Firefox is not the way to do it.

Re: Struggling to get NVIDIA hardware acceleration on Firefox

Same boat regarding video decoding. Not on the system atm, but most coding types seemed blackllisted in about: support and when decoding CPU load rises to 30-40%.

At some point I'll follow the instructions in the link provided by Xephon above.

EDIT: just saw that this was an old thread, soz...

Closing this old thread.

Disliking systemd intensely, but not satisfied with alternatives so focusing on taming systemd.

clean chroot building not flexible enough ?
