Firefox: Hardware video acceleration

I'm on GT 610

libva-nvidia-driver 0.0.14-1
linux-firmware-nvidia 20250708-1
nvidia-390xx-dkms 390.157-17
nvidia-390xx-utils 390.157-17
nvidia-settings 575.64.05-1
opencl-nvidia-390xx 390.157-17

Here's my environment variables

MOZ_DISABLE_RDD_SANDBOX=1
LIBVA_DRIVER_NAME=nvidia
VDPAU_DRIVER=nvidia
MOZ_X11_EGL=1
NVD_BACKEND=direct

But vainfo

Trying display: x11
libva error: vaGetDriverNames() failed with unknown libva error
Cannot load cuvidGetDecodeStatus
libva error: /usr/lib/dri/nvidia_drv_video.so init failed
vaInitialize failed with error code 1 (operation failed),exit

Last time I tried this, it worked but Firefox crashed frequently so I wanna give it a second chance

nvidia-settings 575.64.05-1

Why do you have nvidia-setting instead of nvidia-390xx-settings ?

Re: Firefox: Hardware video acceleration

It's not going to work.

https://github.com/elFarto/nvidia-vaapi … stallation

Requirements

• NVIDIA driver series 470 or 500+

user
I'm using old but descent GT610 fanless card with the latest legacy nvidia driver 390.157. I've read that minimum version is 470 but still trying to deploy you driver and get init error
...
Could you explain, is it totally impossible to implement you driver with 390 driver series?

developer
Yes, it's impossible for it to work on this driver version as it doesn't support DMA-BUF at all, which is required.

Re: Firefox: Hardware video acceleration

Maybe because it's outdated & no longer maintained?
Is it safe to install the 390xx?

It's not going to work.

Oh, I didn't know about that, well then what do I need to do to make better video playback especially on 60fps (Youtube), I tried https://addons.mozilla.org/firefox/addo … d-h264ify/ it helps a bit but still getting consistent frame drops

Nothing you can do basically except getting a new graphics card. If you have iGPU try to use that.

Edit: actually nouveau supports H264 decoding on your card. Hardware acceleration should work using the extension you mentioned in your last post.

Re: Firefox: Hardware video acceleration

nvidia-390xx-dkms , nvidia-390xx-utils and nvidia-390xx-settings are a package deal : use all 3 or none.

I uninstalled them

I tried that but this happened, it's working fine though I could type in my terminal

[    44.893] (==) Using config file: "/etc/X11/xorg.conf"

The unsupported and obsolete messages scattered throughout the log suggest that's made by a tool ()nvidia-xconfig? ) that was useful before X got reliable automagick detection over 10 years ago .

Remove etc/X11/xorg,conf and also xf86-video-vesa .
Reboot (or restart X)  and post fresh xorg log .

Also post the full output of lspci -k

Log looks better, but there is still something hardcoding stuff.
There are some packages that place files in that folder, but not many .

Please post the output of ls -al /etc/X11/xorg.conf.d .

Re: Firefox: Hardware video acceleration

Get rid of libva-nvidia-driver specific environment variables you posted in #1
Set

LIBVA_DRIVER_NAME=nouveau

Did you install additional packages for nouveau https://wiki.archlinux.org/title/Hardwa … ion#NVIDIA ?

Re: Firefox: Hardware video acceleration

And it's still laggy?

What are the values of Compositing and Codec Support Information in about:support?

Re: Firefox: Hardware video acceleration

Still lag. Compositing is WebRender, for Codec Support Information only H264 Hardware Decoding is supported. I might need another browser to compare with cuz it only happens in Firefox

Maybe I mess around too much in about:config

Edit: tried Chromium & Firefox's Troubleshoot Mode, same results
