I have developed my own tiny linux file system using buildroot and busybox. I used linux-18.104.22.168 kernel configured and cross-compiled for target system(X86) according to needs.Now the filesystem is built but it has only busybox shell and it doesn't support GUI.It does not have any package-manager too.Now I want to enable GUI on it. I checked /etc but there was not any x11 directory or x11.conf file.It does not support startx too.
How can I install x11(XFree86 or Xorg) on my system Explicitly. I also want to install a package-manager for my system.
How can this be achieved?
