Closed wanhongbo closed 6 years ago

wanhongbo commented 6 years ago

Hello, I am trying to run more deepin desktop images with x11docker on one machine. And I am use this command to run the deepin images: sudo x11docker --desktop --systemd --gpu --sudouser --homedir /home/sdk/workspace/sdk -- "--privileged -v /dev/kvm:/dev/kvm" x11docker/deepin I use the private nvidia drivers to support openGL APIs,it is no problem when this command is executed firstly.

But when I opened a another terminal and executed the uppper command again,it failed and the error is like the following shows:

x11docker WARNING: Will run DBus system services as root in container.
  If the image contains malicious applications started by DBus service files,
  they may abuse their root privileges and may try to break out of container.

Is there any suggestions?My object is to want to run more desktops in one machine at the same time,Is there any other solution ?Thanks very mych.

Thank you for reporting!

I often run more than one desktop on more than one tty. In general that is not a problem. (I have an AMD GPU with free radeon driver). I assume there is an issue with NVIDIA driver.

Most probably it would work with free nouveau driver.

I think it should work with proprietary nvidia driver, too. I don't have an idea yet, but will think about it.

Thanks for your information.Just now ,I reboot the machine,it can work successfully,I do not know the rootcause,may be the under system have problem.Any any, it can work now.Thanks
