Joypad and Gzdoom

It detects my Dragon inc Generic USB joypad but I can't use it. Using GZDoom libux version on ubuntu natty.

Is the joystick enabled under Joystick Options?

The joystick code only works with the software renderer for some reason.

Now this is strange.

How

That can't be, because mine functions properly. Maybe there's an exception somewhere with his adapter.

So tell me what is software renderer.

Software renderer is where the is engine is displayed in it's original unfiltered graphics

Hardware renderer is opengl filtering with smoothed surfaces.

That's a pretty oriented issue of looking at it.

A software renderer means that all the computations made to draw the images you see on the screen are done by the CPU, using algorithms developed by the programmers. A hardware renderer (OpenGL or Direct3D) means that instead the game only transmits primitive informations to the GPU (not the CPU) and most of the rendering work is done by your graphic chipset. To draw a cube, the software renderer will compute what should be displayed on each pixel of the screen; whereas the hardware renderer will just tell the graphic card that there's a cube of such dimension at such place and let it do the rest.

While OpenGL does support all kinds of filtering, you don't have to use any of them. See the option menus.

To put GZDoom in software mode, open the console and type vid_renderer 0 inside. Too put it in OpenGL mode, type vid_renderer 1 instead. You then have to quit and restart for the change to take effect.

Not quite. The program needs to split it into triangles first.

Not quite. OpenGL supports Quads (4 vertexes, simple, non-intersecting) also.
