black screen appears

[gityeezy]

Hello, I pulled the images of ubuntu22.04 and ubuntu22.04-cu12.2 and followed your tutorial to make the container. However, when connecting with nomachine, a black screen appears. I have used your other versions before and everything was fine.

Linux ye 5.15.0-113-generic #123~20.04.1-Ubuntu SMP Wed Jun 12 17:33:13 UTC 2024 x86_64 x86_64 x86_64 GNU/Linux

it's known bug when use image with tag 22.04 on host ubuntu 20.04，but image with tag 22.04 works well on host ubuntu 22.04，i don't know why.

it can be fixed by add flag --security-opt seccomp=unconfined when you create container with tag 22.04 on host ubuntu 20.04. like this:

docker run -d --restart=on-failure \
    --name my_workspace \
    --cap-add=SYS_PTRACE \
    --security-opt seccomp=unconfined \
    --gpus all  \
    --shm-size=1024m \
    -e USER=ubuntu \
    -e PASSWORD=ubuntu \
    -e GID=$(id -g) \
    -e UID=$(id -u) \
    -p 10022:22 \
    -p 14000:4000 \
    gezp/ubuntu-desktop:22.04
