not at all. you're replying to my mail and acutally
place your comments next to the relevant text from my
previous e-mail. this is the best way of replying and
i wish more people would reply like this, instead of
just writing some text on top or below and quote the
full mail.

ok. so your OpenGL library was replaced by an incompatible
one during the updates.

no surprise here. the livna repository only works with fedora
installations. i suspect the only resolution is now to download
the NVIDIA driver from www.nvidia.com and install it manually.
this was probably done before. the downloadable NVIDIA driver bypasses
the rpm database used by yum and rpm, so the dependency tracking
does not work. every time you update X related libraries or drivers
or the kernel, you'll have to reinstall the nvidia driver (well,
there are some shortcuts, but they'd take too long to explain).

well, it provides the required hint and resolution:

(EE) NVIDIA(0): Failed to initialize the GLX module; please check in your X
(EE) NVIDIA(0): log file that the GLX module has been loaded in your X
(EE) NVIDIA(0): server, and that the module is the NVIDIA GLX module. If
(EE) NVIDIA(0): you continue to encounter problems, Please try
(EE) NVIDIA(0): reinstalling the NVIDIA driver.

cheers,
