Hi ,
I have installed Fedora Core4. I want to wirte an application which directly writes in to the frame buffer.I have seen some sample examples on the net they are using /dev/fb0 to write.When checked in my /dev directory there is no /dev/fb0.
Can I use X11 to directly write in to the framebuffer.I want to write an application to make portion of the screen to be displayed as window.

If you don't have /dev/fbN (where N is a number: N=0,1,2,...) then it would seem to me that you haven't enabled framebuffer in your kernel? If we're talking about the same thing here..

Hi Bouncer,
I have enabled frame buffer console support still it is not showing /dev/fb0 in my /dev directory. Can u just tell me what are the libraries can i use to directly write into the framebuffer.
I want to display the video on the screen.
