Adapting/converting a DX DDS file to OpenGL - how?

[rado84]

I have GIMP (Linux) with DDS plugin which allows the creation/saving of DDS file format. But somehow I'm not sure that will be enough for me to convert DDS files froms mods that require DX to make them compatible with OpenGL. So, what would the pros suggest about that? I'm asking seriously, guys! Graphical modding ain't my strength, I'm more a definition editing guy.

Use Conversion tools that turn .tga into a game ready .dds
