Is there a way to emulate the pixel shading in sofware? I'd like to test some effects on my laptop, which has onboard graphics.

I don't think OpenGL implementations provide a software emulation for fragment programs. Maybe some GPU constructors provide it through an extension, what graphics card are you using ?

While we are talking about postfx, what are the requirements to use it? it says my system doesn't support it.

PostFX use OpenGL fragment programs, so you can check the following extensions :
GL_ARB_fragment_program
GL_ARB_shader_objects
GL_ARB_shading_language_100

You can use this software to check extensions for your GPU or others :

Intel 965/963 Graphics Media Accelerator

Unfortunately, I do not support those extensions.

My desktop machine does though. So I suppose I can just move my SFML program back and forth as needed.

Edit: I looked into NVEmulate, but couldn't get it to do anything.
