I run Kali 2.0.1 on my Rpi 2. I have black areas around my main window (the PI is connected to a 1920x1080 screen), so I thought it could come from the Overscan parameter.
As you probably know, this distro doesn't provide the boot/config.txt file where one can change some parameters as overclocking, display...
So I installed raspi-config in order to fix it, but when I try to change the overscan value, I get the following error : "There was an error running option A1 overscan". I also get an error when I try to expand the file system. Overclocking seems to work (at least I don't get any error).
How can I fix my overscan problem ? Thanks
