I am trying to work with opengl textures and following nehes tutorials with the triangle and the square when I try to add a texture to the square the triangle goes semi transparent in linux and doesnt even show in windows.

I have tracked it down to glTexImage2D that seems to be causing it I am assuming something to do with lighting is that the case? how can I fix it? Thanks

Seems like an issue of alpha blending, but it can only be a guess because one can't tell what code you're talking about here.

Thanks for giving it a shot by searching for alpha blending I was able to find some similar questions that led me to the answer I have to call glDisable(GL_TEXTURE_2D); to draw the direct colors.
