DirectFb installation & accelerator not recognised
 
Hi,
I installed DirectFb on fedora 7, the machine has a Nvidia graphics card. The installation was successful and I can play the examples provided by the Direct fb website, but, I find that the accelarator is not getting recognised. when I do "fbset -i", the details shown are as below, it gives the accelerator as Unknown(46). The output for dfbinfo is also pasted below.

How do I test to know whether the hardware is getting used. When I play any of the Directfb examples with “--dfb:no-software” option, the screen goes blank. Otherwise it play well on the screen.


Can anyone help me on this.
