Comment 7 for bug 2028864

Let me just add nvidia-core22 is geared at Ubuntu Core usage, not Classic (because of problems keeping the kernel driver and userspace in sync).

On Classic, SnapD exposes the proprietary Nvidia pieces in `/var/lib/snapd/lib/gl`. This is normally handled by snap wrappers (e.g. https://github.com/ubuntu/snapcraft-desktop-helpers/blob/ec861254c2a1d2447b2c589446e6cdf04c75c260/common/desktop-exports#L103-L109), and supported by mesa-core22.

So while moving snaps to graphics-core22 is an important piece on Core, it not working on Classic suggests something else needs looking at.

Check out https://snapcraft.io/graphics-test-tools, hopefully it can give you some insight as to what's missing.
