For those who are waiting for the latest NVIDIA 565.77 driver package, it’s now available in PPA for Ubuntu 22.04, Ubuntu 24.04, and Ubuntu 24.10.
NVIDIA 565.77 is so far the latest feature branch version graphics driver for Linux. As Ubuntu seems to prefer the production branch version, this new driver release will be less likely (in my own opinion) to be add into official system repository.
If the new driver includes specific features and bug-fixes for your device, then you may try the “Graphics Drivers” team PPA maintained by Ubuntu Team members.
