Hi Adam,

No problem, I only found out about the alternatives system because I
noticed that Xorg could not find the correct .so files to load the
nvidia glx and I just followed the symlinks.
I think you are right that the alternatives system only works on
debian based systems, but for my Kubuntu 10.10 system that is enough.

The update-alternatives command is actually not that difficult, it
just sets the (Open)GL configuration to either the mesa directory or
the nvidia directory. Note that I have not created anything, all this
is already present on any Ubuntu system. So it will work for anyone
with Ubuntu and will also continue to work even after updating mesa or
nvidia on those systems (I hope :P).

I haven't used the nvidia installer directly, I just use the
nvidia-current packages of (K)Ubuntu and these packages take care of
updating the alternatives system. I don't know if the nvidia installer
itself also does that.

For other distros there might be a different system...

Regards,

Rutger
