Question glxinfo "couldn't find rgb glx visual or fbconfig" on nvidia drivers

I have a weird one. If I run glxinfo I get "couldn't find rgb glx visual or fbconfig".

But if I run sudo glxinfo it works fine. If I run glxinfo as root (sudo -i) I get the error.

Any ideas where I start looking?

Well, I had the same error just a few minutes ago, and fixed it by un-installing lib64mesagl* (all of them).

Then reinstalling them,

urpmi --noclean lib64mesagl -a
7 files were reloaded, including devel packages.

Then I ran, (this might do you)

sudo ldconfig -Cfrv && sudo symlinks -csrv /
It would be irresponsible of me to not say, "check the man pages for these commands".

then when I run glxinfo it comes up with the lines of details (that make no sense to me, but... lol)

glxgears works too.

Hope this helps you.

Regards Glenn

problem solved.

I found the problem. Seems the kmod drivers for nvidia are broken. I used the sh file directly from the nvidia site and it work no problem.

When Fedora updates the X-server it replaces the GLX drivers with the Xorg ones. This, generally, breaks propitiatory drivers.

Note: I've been trying to use the nVidia driver on Fedora 12 (alpha), but - so far (I haven't tried for a couple of weeks) - it fails to load because at least one symbol that nVidia assumes is in the kernel is no longer defined.

Note also that (again, so far) the nouveau driver crashes the (new) X-server fairly frequently (on my hardware). Which is why I've tried to install the "stock" nVidia driver.
