Comment 10 for bug 511872

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.
