Jetson AGX Xavier not displaying

Help me.
Suddenly the screen disappeared.
I use Jetson AGX Xavier.
I installed deepstream 5.1 via hostPC a few months ago.
I tried some deepstream samples and trt-pose samples.

Since docker was required, when I entered the following command from ngc, there were many errors that Jetson’s capacity was insufficient, so I deleted the data each time.

docker pull nvcr.io/nvidia/k8s/container-toolkit:1.4.7-ubi8
distribution=$(. /etc/os-release;echo $ID$VERSION_ID) \ && curl -s -L https://nvidia.github.io/nvidia-docker/gpgkey | sudo apt-key add - \ && curl -s -L https://nvidia.github.io/nvidia-docker/$distribution/nvidia-docker.list | sudo tee /etc/apt/sources.list.d/nvidia-docker.list
(I referred to the following site:
Installation Guide — NVIDIA Cloud Native Technologies documentation)

The deleted data is below home directory, and I do not intend to delete important directory. And I restarted once.

After turning on the power, the nvidia log will be displayed, and then the following will be displayed.
cp: not writing through dangling sylink'etc / resolv.conf
cgroup: cgroup2: unknown option "nsdelegate"
random: crng init done
random: 7 urandom warning (s) missed due to rate limiting
using random self ethernet address
using random host ethernet address
using random self ethernet address
using random host ethernet address

After that, a black screen is displayed.
I entered the command ctrl + alt + F1-F6, but the screen remained black.

After about 5 minutes, these was displayed again as shown:
cp: not writing through dangling sylink'etc / resolv.conf
cgroup: cgroup2: unknown option "nsdelegate"
random: crng init done
random: 7 urandom warning (s) missed due to rate limiting
using random self ethernet address
using random host ethernet address
using random self ethernet address
using random host ethernet address

However this time, the screen did not go black and continued to be displayed. And then, when I entered ctrl + alt + F2, the TeleTypewriter was displayed.

Is there a way to flash and start over?
If you have the information you need to solve this problem please let me know how to get that information.

Thank you.

There is no update from you for a period, assuming this is not an issue any more.
Hence we are closing this topic. If need further support, please open a new one.
Thanks

Please use the tty console and dump me the log of /var/log/Xorg.0.log.
