This change was made by a bot.

[jeremyszu (os369510)]

how about launch Terminal and then issue:
$ glxinfo | grep -i opengl

[Kevin Yeh (kevinyeh)]

I tried glxgear before, it will use nvidia-driver, I can see it by nvidia-smi.
Since we define our test scope using firefox to check, so I report this bug.
Or should I add firefox as impacted package and remove linux package.

[Sebastien Bacher (seb128)]

the issue is not likely a kernel one, reassigning to firefox

[Pierre Equoy (pieq)]

I just filed lp:1967478 before finding this issue... There might be additional information there.

[Akshat Singh (hackerdagreat57)]

Can confirm, even with `switcherooctl launch firefox` it doesn't use the Nvidia GPU.

[Gon Solo (gonsolo)]

Ubuntu's firefox runs with llvmpipe as GPU. I downloaded firefox from mozilla.org and it correctly uses my NVIDIA RTX 3060.

Also Google Maps can't be run in 3D mode with llvmpipe. It works with Firefox Nightly from Mozilla.
