NVIDIA Driver Not Installing #171

Closed sjordahl closed 5 years ago

sjordahl commented 5 years ago

Wanting x11docker to install the NVIDIA driver in a container, but something (possibly the error) getting in the way. Using x11docker --hostdisplay --gpu <image> DOES work, but the attached config doesn't do the install. x11docker.log

Hi Steve, nice to hear from you!

I recently fixed some issues around NVIDIA in master version. Could you please update with x11docker --update-master and try again? If the master version works, I'll publish a new release soon.

sjordahl commented 5 years ago

Thanks for the quick response. The master DID start to install the driver, which the previous version did not. But it's erroring out.

Will upload a log in a bit.

Here's the log: x11docker.log

mviereck commented 5 years ago

I probably found the reason. Your command:

'/usr/bin/x11docker' '-D' '--hostdisplay' '--gpu' '--env' 'VRDE=off' '--env' 'VBPORT=33389' '--cap-default' '--hostnet' '--' '-v' '/home/jordahl/workspace/vms/windows/Windows:/vm' '--device' '/dev/vboxdrv' '--cap-drop=ALL' '--' 'steve/virtualbox:6.0.8'

The command contains --cap-default -- --cap-drop=ALL to fit your VirtualBox setup. However, --cap-drop=ALL causes the NVIDIA installer to fail. Please try without --cap-drop=ALL.

Background: The NVIDIA installer needs several capabilities and must not run with --security-opt=no-new-privileges. In this special case your VirtualBox setup would even run without --cap-default because x11docker adds some privileges to allow the NVIDIA installer.

Great call! The driver did install, and worked as expected. Thanks for the assist! Now to figure out why vbox 3D acceleration is making some of my window panes black...

As always, your help is very much appreciated!

:-) You're welcome!

That is probably a VirtualBox and/or NVIDIA issue. However, if you assume it is related to x11docker, please tell me. I never had a satisfying VirtualBox GPU setup even with other graphics cards. I did not try for a long time, though.

sjordahl commented 5 years ago

Agreed, this is not an x11docker issue. I think it might be a NVIDIA/WDDM issue.

Some years ago I had an experimental setup with Linux host and Linux VM: The applications in the VM has been connected to the X server from host and used the host GPU flawlessly. I am not sure how I accomplished that; probably I set up an X server with -listen tcp and set DISPLAY in the VM with IP:DISPLAYNUMBER. Edit: Or did I share the unix socket and softlinked it within the VM to /tmp/.X11-unix?
