Comment 2 for bug 126251

Interesting. I've removed the duplication. For some reason, I still have /usr/share/applications/NVIDIA-Settings.desktop installed locally, although I can confirm it is no longer supplied by nvidia-glx-new.

Separately, regarding the icon, my understanding is that Ubuntu has not been granted a license to redistribute the nVidia icon for the .desktop file. If this is not the case, it should indeed be used.
