Does this card require non-free firmware?
- Anmelden oder Registrieren um Kommentare zu schreiben
I would appreciate any advice on how to determine whether a given NVIDIA GPU should provide hardware 3D acceleration without non-free firmware. I couldn't find on h-node the card that I am checking. The "nouveau FeatureMatrix" seems to only track the driver functionality. I assume that the proprietary driver "firmware" that it mentions is the code that the nouveau driver attempts to replicate. There may also be firmware that the kernel may still require to initilize the card to make those features available, correct? The Gentoo wiki page for NVIDIA seems to suggest that older and newer cards should work with nouveau, while NV110, NV130, and NV140 are only partially supported. However, I do not understand how they deduce that from the "FeatureMatrix", which they refer to. So, I am not sure what card, any card, to look for instead.

I tried disabling the firmware loading with kernel parameter nouveau.config=NvGrUseFW=0 but this seems to be ignored.

I recently went through this myself, purchasing a GT 1030 based on information that seemed to suggest 3D hardware acceleration would work without the proprietary firmware. It doesn't.
I can confirm that a GT 710 does, and I speculate that a GT 730 or GT 720 likely would too (I would have bought one of those, but after wasting money on the 1030, I didn't want to pay more than I had to on another card that might not work). From all that I've read, any NVIDIA card more recent than the 7xx series (Kepler) won't work very well without proprietary firmware.
I'm sorry that I can't provide any more general advice as requested, I've found the documentation is quite hit-and-miss.
My 780 works just fine with Trisquel.
