Thanks, Daniel. That makes sense.

Given the correction to bug 2155202, I think this report should probably
be treated as either related to, or possibly a duplicate of, bug 2155202
— but with one specific Jammy/Kepler datapoint:

On this Mint 21.3 / Ubuntu Jammy system, `nvidia-driver-470` is no
longer a safe package path for a GTX 760, because it resolves toward the
535 branch, and 535 does not support this GPU. The result is not merely
that 470 is EOL; the transitional path selects a driver branch that the
NVIDIA kernel message says will ignore the card.

The current `470-server` packages restored this system for now:

```text
Kernel driver in use: nvidia
driver: nvidia v: 470.256.02
X loaded: nvidia
OpenGL renderer: NVIDIA GeForce GTX 760
nvidia-driver-470-server Installed: 470.256.02-0ubuntu0.22.04.1
```

However, if `470-server` is also going transitional, then that
workaround should be considered temporary/fragile.

So the user-facing guidance seems to need clarification. For Jammy users
with Kepler GPUs, the current options appear to be:

1. use nouveau,
2. keep/pin/hold a working 470 or 470-server package set,
3. use a third-party/community repack at their own risk,
4. or avoid the transitional 470 packages until the regression in bug 2155202 
is resolved or clarified.

The important part is that “transition 470 to 535” is not a working
migration path for Kepler users.
