What sort of gpu?  Nvidia and AMD tend
      to be quite different.



      Nvidia tends to use Cuda framework, AMD uses OpenCL.  They offer
      some level of compatibility I think, but nothing I've particularly
      used outside of pure  graphic opengl for gaming and desktop
      compositing mostly.  Each tends to be better at certain uses as
      well depending on the type of functions invoked in their process
      engines.


      Using AMD with bitcoin mining for a bit, you had to install opencl
      libs under ubuntu, bind the app at the socket level to the gpu,
      and not do anything to the system that needed much graphic use
      beside that.  Blender or Hugin if using GPU, probably much the
      same.  Nvidia will have a cuda equivalent.  The googles are your
      friend for your particular case to get the appropriate libraries
      there.


      I'd recommend using a window manager that doesn't composite if
      they peg your gpu.  Install psensor and watch your gpu temps to
      see how much they're scorching it.  Powertop would be fun to watch
      as well when in use, running a bitcoin miner on mine caused it to
      go into furnace mode.

I'm working with hugin right now at this moment and
        it is rendering a gigapixel image (WOW). Anyways I was looking
        at the text at the beginning of the process and it says:




   Using GPU for remapping: false


I think I bought a video card! How can I find out the
            capabilities of my video card? lspci didn't say anything
            special.
