In other words, when you installed the new driver. This is different
from the kernel update. Installing the new kernel did not kill the
driver, as you purport. Installing the new driver did.

Because its a pain in the butt and a waste of time. It would be one
thing if the build worked every time, but about half the time it
doesn't.
Agreed. That's why I've switched to the Livna driver. It just works.

What is the reason why nvidia can't release source to the kernel
people ?
I mentioned this in a previous email. nVidia does not own all of the
Intellectual Property involved in their graphics cards and their
driver. They cannot give away what is not theirs, so they are legally
prohibited from releasing the driver source. Sorry, but that's the
way it is. Look around for the issue on the web. I've seen this
stated several times by people from nVidia.
What prevents the OS people from putting a wrapper around the Windows
version of the driver ?
That's essentially what the nVidia binary driver is. For the most
part, it is the same code as the Windows driver (as I understand it,
at least). There is a small bit of source code that connects the two
(what you actually build when installing it).
Any chance the NVidia driver could be reverse engineered, especially
since we have examples built for the Linux kernel ?
Sure. Some people have worked on that, even. The problem is, nVidia
has a nasty habit of developing new cards that are faster and fancier
and have new features :-). You cannot keep up. Oh, and that IP issue
above is also why nVidia cannot give out the details needed for
someone else to write an open source driver.
I'm not a kernel developer, so please excuse my naivety.
I'm not either, but I've seen the issue discussed many times (several
on this list...). Graphics cards are about as complex as they come.

It has been my experience that merely running the new kernel will break
the driver for the old kernel. Like it did this morning. I don't
understand why.
I thought you said it didn't break until you installed the new driver?
Running the new kernel should not break the driver for old kernel, as
far as I know.
Question: why does the old driver have to be uninstalled for the new
driver to be built ? I'm guessing it doesn't reside in the modules
directory like other kernel modules ? Even fixing that would be a step
forward. At least one could step back to old kernels.
If you install a new version of the driver, then the old one has to
go. There are bits that get put somewhere besides the modules
directory and you cannot have two versions of this. Now, by default,
even if you install the same version, I think it will remove the old
kernel module. Look at the -k and -K options for the nvidia
installer. One of them is used to specify the kernel version (if
other than the currently running one) and one says only install the
kernel module, which causes it not to remove the old driver. I'm not
sure why this is not the default. But, when you cross a version
number, you have to remove the old one.

The Linux driver model is preferable by far.
I agree, at least to some extent. As long as your hardware is
supported, it's great. When it's not and you have to get an out of
tree or binary driver, it's not so great. Which is why we are having
this discussion... :-)

Yes, but you don't have to build them ! The issue is that the drivers
have to be built, because if you look at the errors, that is where they
are occurring. SELinux gets in the way, the kernel headers have to be
installed, files are missing or renamed in the kernel, gcc is the wrong
version, etc, etc, etc.
You can go to Livna and not have to build them as well. Have I said
that before? :-) Which point are we going to debate where?

Its different as explained above.

I know about livna, etc. But just because its a solution does it mean
its reasonable ?
Valid point. A solution is not necessarily reasonable just because it
is a solution. Is there a better, more reasonable solution? Or what
is not reasonable about this solution?

And which one would that be ?
I'm not sure. Many distros have gone to an OSS only approach. nVidia
only recently modified the license to allow distros to redistribute
their driver if they so choose. Fedora chooses not to, because the
driver is not OSS, because nVidia cannot release the source...

Yes !
Really? It seems that most of the zombied Windows boxes out there are
cracked because someone has neglected to update the thing, which would
have plugged the hole. You always have the choice not to update. It
may not be the best choice, security-wise, but it is a choice.

I don't buy that.
Why not? If all the distros are the same, what's the point in having
multiple distros. Fedora has some features to it that do not
necessarily make it right for a first-time Linux user. I don't mind
that; I can deal with it. It is getting better, though. A lot of
things just work, and that's great.

Yeah, that is part of it. I got my nvidia driver working this morning.
This is a general usability issue.
Okay, well, let's keep things organized here. So your mom cannot
handle updating the nvidia driver. Fine. Let her use the nv driver.
Or the Livna package. Or you do the updates and fix it for her. Or
don't buy an nVidia card or a laptop with an nVidia card. As far as
fixing nVidia, I'm not sure there is much we can do there,
unfortunately.

Yeah, visit a forum and muck around and then apply patches and compile.
Fun. Totally unnecessary.
Right. Just use the Livna package ;-).

Because I haven't had a single issue with the ntfs driver. Never, none,
zero.
Try the Livna package and see if you have any trouble with it. If you
like the Livna NTFS driver, you'll probably like the nvidia driver as
well.

The issue isn't that it can't be made to do this and that and work in
general. Because it can. And I am sure we can all become experts on
installing nvidia drivers. Its totally unnecessary ! If nvidia would
give the kernel developers some info, we wouldn't have to put up with
these work arounds.
Yes, it's not ideal. But that's where we are. See above for the IP
issues involved. IP is big business.

Well then I guess we would never have computers in the first place
because the early computers didn't do much more than we could do in our
head !
Huh? But they could do it faster, more accurately, and for hours on
end. There were advantages to computers when they were first
developed. I'm not saying don't question the status quo; sometimes
that is necessary. But if you do, don't do it in a way that will make
people mad (again, see your subject line). First, see what solutions
are out there. If one works, great! Use it! If you don't like it,
voice your opinion and back it up with facts. Offer other
suggestions. You seem like you bring this up so that the issue can be
addressed and hopefully improved, but for the most part, you have not
gotten people's attention in a good way.
If you don't like nVidia and using the driver, I'd suggest when you
purchase your next computer, don't buy an nVidia card. Personally, I
think nVidia is doing the most for Linux of all the graphics card
companies, so I support them. Yeah, Intel has open source Linux
drivers, but are they as good as the Windows drivers? Is the hardware
as good as nVidia's? Can I use an Intel graphics card with my AMD CPU
that I prefer? Maybe you can find something that works better for
you, but for me, nVidia works.
