Accessing frame buffer device in Core 4.7.7

[georgp24]

I try to run an application that accesses the frame buffer on Core 4.7.7. This fails to open /dev/fb0.

When I boot a CD with a plain Core 4.7.7. image on it I can enter "ls /dev/fb0" and see this file is present. But if I enter "sudo wc /dev/fb0" I get "can't open '/dev/fb0' No such device. The same result I get when I enter "sudo cp /dev/fb0 ."

What needs to be done so I can open /dev/fb0 ?

Please post output of "fbset".

Did you install the xf86-video-xxx.tcz that corresponds to your hardware?

[georgp24]

When I enter "fbset" I get: "can't open '/dev/fb0' No such device".

I did not install any xf86-video-xxx.tcz driver since I did not want to use X but just the frame buffer device directly. That is why I try to use Core und not TinyCore.

You need to boot in a framebuffer mode to have the device exist. One of the vga= bootcodes for example.

Pooh! Thank you very much curaga, this seems to work!
