Background color Framebuffer console

Background color Framebuffer console

[Amol Lad]

Hi,

After enabling console on framebuffer, the background color is "blue"
. How can I change this color (to say black) ? Is this color specified
by vc->vc_video_erase_char ?

Thanks

background color should be "black" by default. What is the endianness
of your host CPU and of the frame buffer?

To set black background try

# echo -e "\033[40m" > /dev/tty0

You could also try to set other bg colors and see what happens:

# for ((i = 40; i < 51; i++)) do echo -e "\033[${i}m > /dev/tty0"; done

No, it is not specified by vc->vc_video_erase_char but by upper nibble
of vc->vc_color, IIRC.

Best Regards,
Anatolij

The above command should be 

# for ((i = 40; i < 51; i++)) do echo -e "\033[${i}m" > /dev/tty0; done

Sorry, my typo.
