frame buffer error part2

After the zImage has been generated, I boot up uClinux but I am unable to run:

nano-X &

nxterm &

and the rest of them...the nio-terminal says bad command or filename

I have followed the directions on your wiki step by step but I get this error:

    i didn't check the .tar.gz, but it should be the same.

    did you apply the nios2 patch once?

    can you find uclinux-dist/lib/libjpeg ?

    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?

    It is running as process number 20. It should be OK. You can check the VGA screen.

    There should be an arrow cursor on the screeen.

    If you have mouse, you should be able to move the cursor.

    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&#39;t select virtual terminal in my menucongif.

    It is OK. It is already selected.
