frame buffer error part2

Hello!

I compiled TAR.GZ (from uClinux.org) with frame buffer and nano-X with no error.

I see message fb0: Altera frame buffer device, using 600K of video memory.

But when I wrote nano-X & in sdk shell it return [20]. What it means?

Also I found some distinction in menuconfig. on my PC:

Device Drivers --> Character devices --->

--- Virtual terminal

[ ] Support for console on virtual terminal

...

But on nioswiki

Device Drivers --> Character devices --->

[*] Virtual terminal

[ ] Support for console on virtual terminal

so I can't select virtual terminal in my menucongif.
