Description:
The two files inside /usr/share/applications: nsight.desktop and nvvp.desktop uses hardcoded icons (explicit uses the full path instead just the icon name):
nsight.desktop: Icon=/opt/cuda/libnsight/icon.xpm
nvvp.desktop: Icon=/opt/cuda/libnvvp/icon.xpm

There is no desktop file inside the upstream package or also in ubuntu package for example.

The problem is because the icon theme developers can't change the icon for this application, in other words: these icons will be inconsistent in design theme.

Additional info:
* package version(s): cuda 6.5.19-1 x86_64

Steps to reproduce:
- Create an icon named "nsight.png" and "nvvp.png" inside your icon theme folder.
- You will check that this icon will not replace the default one.

You can check the desktop files by the following commands:
$ cat /usr/share/applications/nsight.desktop | grep "Icon="
$ cat /usr/share/applications/nvvp.desktop | grep "Icon="

Steps to solve it:
- Create a symbolic link for these two files:
/usr/share/pixmaps/nsight.xpm -> /opt/cuda/libnsight/icon.xpm
/usr/share/pixmaps/nvvp.desktop -> /opt/cuda/libnvvp/icon.xpm

- Modify /usr/share/applications/nsight.desktop file:
from: Icon=/opt/cuda/libnsight/icon.xpm
to: Icon=nsight

- Modify /usr/share/applications/nvvp.desktop file:
from: Icon=/opt/cuda/libnvvp/icon.xpm
to: Icon=nvvp

Steps to solve - description:
Creating the symlink and changing the desktop files will allow the icon be loaded normally by .desktop files as before, however it will give the possibility to icon theme developers use their own icons for this app, making the desktop design consistent.
