--gpu doesn't install drivers automatically anymore

[01e9]

1. The x11docker script
2. The driver is prepared in the right directory
3. Output doesn't contain "installing driver..." and container starts fast.

Thank you for the report!

I did a test run with the current master version, it works well so far.
Can you please show me the output with option --debug? What is your x11docker version?

Maybe this check fails, could you please try it out?

head -n1 2>/dev/null </proc/driver/nvidia/version | awk '{ print $8 }'

It should print 390.116 on your system.

With --debug https://pastebin.com/raw/6BhncsRy
Driver version and installer are detected properly but installation is not starting.

Ok, it is fixed now.
It only happened along with --cap-default, so i missed it first. It was only one : missing in the code. :)
Please update to current master. I'll publish a new release soon.

Fixed. Thanks!

I did a change in latest commit that affects the NVIDIA driver installation, too.

x11docker's root setup in container now runs with --privileged flag. This gives all privileges that are needed to install the driver. The final container command on the other hand does not need or get any privileges anymore.

Could you please run two tests for me?
This should just work and show the NVIDIA card name:

x11docker --gpu x11docker/check glxinfo | grep renderer

This one might fail:

x11docker --gpu --init=systemd --newprivileges=no x11docker/check glxinfo | grep renderer

I need to check if --newprivileges=no makes a difference here.
With --init=systemd x11docker takes another code path that does not give --privileged to containerrootrc.

Background:
Earlier the NVIDIA driver did not need --newprivileges=yes. Later the driver installation failed and needed --newprivileges=yes (automatically enabled).
Now it works in my tests with --newprivileges=no again.

It is confusing and I assume that there has been a docker bug for some time.
With my current Docker version 19.03.5 the installation succeeds with --newprivileges=no.

Thank you!
So it seems the driver installation succeeds again without --newprivileges=yes. Maybe I can disable that in the code again.
It has been an issue in #162. I'll ask there for a check, too.
