玲珑firefox怎么开启nvidia显卡硬件加速

已在小UI和论坛大佬帮助下解决，但并非最小路径，后续可找一下最小路径。

小UI答案@20260914

安装nvidia-vaapi-driver

并配置好本地端加速正常，特别是：

ethan@4060TI:~/.linglong-firefox-vaapi$ cat /etc/default/grub | grep nvidia
GRUB_CMDLINE_LINUX_DEFAULT="video=efifb:nobgrt splash quiet loglevel=0 locales=zh_CN.UTF-8 nvidia-drm.modeset=1"
ethan@4060TI:~/.linglong-firefox-vaapi$ cat /etc/environment
# Controls which backend this library uses. Either egl (default), or direct. See direct backend for more details.
NVD_BACKEND=direct
# Disables the sandbox for the RDD process that the decoder runs in.
MOZ_DISABLE_RDD_SANDBOX=1
# For libva versions prior to 2.15, this forces libva to load the nvidia backend.
LIBVA_DRIVER_NAME=nvidia
# Required for the 470 driver series only. It overrides the list of drivers the glvnd library can use to prevent Firefox from using the MESA driver by mistake.
_EGL_VENDOR_LIBRARY_FILENAMES=/usr/share/glvnd/egl_vendor.d/10_nvidia.json

安装论坛指导包

https://github.com/NVIDIA/libnvidia-container/blob/gh-pages/stable/deb/amd64/nvidia-container-toolkit-base_1.20.0-1_amd64.deb

对应目录https://github.com/NVIDIA/libnvidia-container/blob/gh-pages/stable/deb/amd64下的8个软件包

关键配置（小UI完成）

上述，库文件来源：

cp -a /usr/lib/x86_64-linux-gnu/libgstcodecparsers-1.0.so.0* /home/ethan/.linglong-firefox-vaapi/lib/
cp -a /usr/lib/x86_64-linux-gnu/dri/nvidia_drv_video.so /home/ethan/.linglong-firefox-vaapi/lib/

实测

重启之后，通过图标启动firefox即可。

ethan@4060TI:~/.linglong-firefox-vaapi$ nvidia-smi dmon
