Jetson agx orin:After the kernel is compiled successfully, reboot with a black screen

I followed the steps below to compile and install the kernel. I was able to compile and install the kernel successfully, but the graphical interface was not displayed. I can now control it only through the serial console。The steps are as follows:

sudo make mrproper
make O=$TEGRA_KERNEL_OUT tegra_defconfig
make O=$TEGRA_KERNEL_OUT menuconfig
sudo nano .config# modify LOCALVERSION=‘-tegra’

Compile kernel image and kernel modules

time make -j12 Image
time make -j12 modules

Install modules and kernel image

$ sudo make modules_install
$ sudo cp arch/arm64/boot/Image /boot/Image

sudo depmod -a
sudo reboot
