Linux buildroot我得到一个xorg黑屏

我正在用Buildroot构建一个小的Linux映像。我将图像加载到Qemu中，得到一个黑屏

default ----> pc_x86_64_bios_defconfig

我所做的配置更改是：

Toolchain ----> Enable C++ support
Target packages
       Show packages that are also provided by busybox

Graphic libraries and applications (graphic/text)
       X.org X Window System
              X11R7 Servers ----> xorg-server
              X11R7 Drivers ----> xf86-input-evdev,xf86-input-keyboard,xf86-input-mouse,xf86-video-cirrus,xf86-video-fbdev
       xterm
       openbox

Filesystem images
       exact size ----> 200M
       initial RAM filesystem linked into linux kernel

然后我使用运行脚本：

qemu-system-x86_64\
-内核/bzImage\
-追加“console=tty0”\
-initrd rootfs.cpio\
-M2g
