Just did a fresh install of 10.04 amd64 Desktop on my daughter's laptop.
Activated the nvidia-current drivers for the chipset and found that
every 3D application I tried (all of which worked on the system with
9.10 386 Desktop) complained about missing 3D support in one form or
another.

Oddly enough, my similar laptop was upgraded from 9.10 amd64 Desktop to
10.04 and had no issue running any of the applications that failed on my
daughters.

Digging a bit I found that glxinfo would segfault every time on the
fresh install but yet work perfectly on the upgraded machine.  Further
digging revealed that X was apparently running completely autoconfigured
on the fresh install.  That is, there was no xorg.conf of any kind.
While the upgraded system had a minimal xorg.conf specifying only a few
options.  Copying the minimal xorg.conf that explicitly loaded the glx
module to the freshly installed system seems to have completely fixed
the issue.

I've attached the minimal configuration to this report.
