Nvidia switched to defaulting to the open source driver module in driver 560. As of 565.77 we've also made the same switch. The open-source Nvidia driver does not support pascal (10 series) and older because it requires GSP firmware, which those cards are not capable of.
The lowest supported chips are the GTX 1630 and MX 450 (mobile only):

Anything before Turing is not supported.
If you are still unsure if your GPU is supported by the open driver:
Supported by current open driver:
GeForce RTX: 40 Series, 30 Series, 20 Series
GeForce: 16 Series
NVIDIA Turing: T4, T4G
Supported by closed proprietary driver:
GeForce RTX: 40 Series, 30 Series, 20 Series
GeForce: 16 Series, 10 Series, 900 Series, 700 Series
NVIDIA Turing: T4, T4G
NVIDIA Volta: V100
NVIDIA Pascal: Quadro: P2000, P4000, P5000, P6000, GP100; Tesla: P100, P40, P4
NVIDIA Maxwell: Quadro: K2200, M2000, M4000, M5000, M6000, M6000 24GB; Tesla: M60, M40, M6, M4

It should be additionally noted, Nobara 41 and higher do not ship with X11 packages and also does not support X11 moving forward.
