We need a solid test plan to ensure that Nvidia does not break

X11Libre needs to use the same ABI that Xorg uses as I doubt nvidia will add support for it.

And someone else

What I think Xlibre needs in the first place if it’s to move forward, are solid end2end tests preventing regressions.

I tend to agree with both.

So I think this project needs to put tests in place that ensure compatibility with Nvidia does not break.
If I was Nvidia, I'd not bother to test against two X11 implementations. So as long as upstream is still "alive", it is reasonable to assume that they will test their drivers (only) against that and not some new fork. This might change over time (think LibreOffice vs. OpenOffice), but for the time being, that's how it is.

Hence, this project needs a robust plan how to test each release for Nvidia binary compatibility. Against all the various Nvidia driver version families.

Right now I don't know how to do this, but that's the beauty of the community - someone usually knows how to do things.

Thank you for your contribution! We currently restructured the "Ideas" discussions and accordingly this discussion will be moved to the X11Libre 3 Ideas Soon To Be Addressed · Discussions · GitHub category.

There are already some ideas of how to do these tests. They could be both manually and automated. I'll come back to you soon.

would it be possible to reach out to Nvidia such as their official forum about what information they can provide or what they can do on their end to make this easier to implement?

How difficult would it be to implement GBM or whatever Wayland uses for its drivers, so if the X11 driver is ever dropped the wayland driver can be used?
