GUI Apps in LXD container

First of all, I suggest to run xclock as a primary test to see whether the container can run GUI applications on your desktop. glxgears and glxinfo require a bit more from the X server, and may fail even if xclock is working.

When you created the gui1804 container, you assigned two profiles, default and gui (in this order).
This assignment is something that LXD remembers for you, and applies to this container whenever you start/restart it.

To edit a profile, you use lxc profile edit gui. It opens up your default text editor and lets you edit verbatim the profile configuration. Then, when you exit/save, the profile is changed.
Finally, you just need to restart the container (lxc restart gui1804) and it will update to the new configuration. That means that it will recreate the appropriate Unix sockets.

Regarding the change, try both cases that you list there. I am not familiar with X1024, therefore you are investigating as well on what should be put there.

Hi @simos
nothing seems to work.
however I just done the following

sherab@Sherab-PureOS:/tmp/.X11-unix$ stat X0
  File: X0

sherab@Sherab-PureOS:/tmp/.X11-unix$

And I find it interesting that the size of both the X10 and X1024 are 0 - does it mean the file is empty?

also do you think it might do anything with this:

sherab@Sherab-PureOS:~$ lxc exec gui1804 bash
root@gui1804:~# xclock 
No protocol specified
Error: Can't open display: :0
root@gui1804:~# xauth list
xauth:  file /root/.Xauthority does not exist
root@gui1804:~#

First of all, you try to run GUI apps as root in the gui1804 container. That will not work without additional work not described in the tutorial. Please try again as user ubuntu.

Second, the Unix socket file are of size zero. They are special files that are associated with some running process. Without that running process, these file do not do something and have no content.
To see the Process ID of the associated process, run

$ sudo fuser /tmp/.X11-unix/X0 
/tmp/.X11-unix/X0:    2299

Perform the following only if you still get issues about Xauthority, when you connect as ubuntu in the gui1804 container. I wrote the following without noticing first that you connected as root to the container.

With this line in the gui profile, we are normally able to avoid copying the .Xauthority file from the host to the gui1804 container. In your case it does not appear that we can avoid that, therefore you would need to follow the older guide for the .Xauthority file, at https://blog.simos.info/how-to-run-graphics-accelerated-gui-apps-in-lxd-containers-on-your-ubuntu-desktop/

In a nutshell, you would need to additionally run the following,

 lxc config device add gui1804 Xauthority disk path=/home/ubuntu/.Xauthority source=${XAUTHORITY}

See the older blogpost for an explanation of the command.

I am very happy to inform that YES both xclock and glxgears are working!!
Thanks @simos

Thank you for your patience.
Now for my next jobs

  1. install crossover in my gui container on PureOS [which I managed installing crossover on lxd gui container in my linux mint 19.1]
  2. Install scapple inside that container and then run the scapple application with the crossover [in my gui container on my linux mint I managed running crossover and started installing the scapple file but there were some error messages]

Many many for you healp and again thanks for your patience - I appreciate you guys are busy with your life and yet you take the time to patiently guide people like me

Much appreciated

I read about the root and lxd mappings in https://stgraber.org/2017/06/15/custom-user-mappings-in-lxd-containers/

Any idea what is the matter? @simos?

Hi!

The problem you are facing is with the ID mapping. The error message is

Failed to set up id mapping.
newuidmap failed to write mapping "newuidmap: uid range [0-1001) -> [100000-101001) not allowed": newuidmap 7782 0 100000 1001 1001 1001 1 1002 101002 64534

The relevant configuration that could cause this issue is

  raw.idmap: both 1001 1001

But what does both and these two numbers actually mean? Contrary to the popular belief,
the first number is the UID and GID for the non-root user on the host.
The second number is the UID and GID for the non-root user in the container.

Which means that for your case, with UID/GID 1001 on the host, you should have used instead

  raw.idmap: both 1001 1000

because the Ubuntu LXD container images default to UID/GID 1000 for the ubuntu account.

You can edit the profile by running lxc profile edit gui, and change the 1001 into a 1000.

Hi @simos,

Thank you for your detailed reply. I can confirm that it now works. I believe your blog post may require a correction when you comment about lxc profile set gui raw.idmap "both 1001 1001". I didn’t read all the comments there but should have, since the last commenter at the time of writing pointed it out as well.

Anyway, got GUI applications working now, thanks a lot!

Hi @simos,

I have also been following your blog posts to try and get gl support into my containers.

In my case I have an Ubuntu 18.04 host (amd64) and an 18.04 (amd64) container.

The host is using nvidia-driver-340 and the container has libnvidia-gl-430:amd64 and deps.

User mappings and display sharing should be working correctly as xclock and xterminal are working fine, the problem arises when I try to glxinfo from inside the container:

ubuntu@gui64:~$ glxinfo
name of display: :1
X Error of failed request:  BadValue (integer parameter out of range for operation)
  Major opcode of failed request:  154 (GLX)
  Minor opcode of failed request:  24 (X_GLXCreateNewContext)
  Value in failed request:  0x0
  Serial number of failed request:  85
  Current serial number in output stream:  86

I am trying to debug the error, but I cannot find pointers to what is wrong, only thing I noticed is:

romen@host:~$ sudo cat /var/snap/lxd/common/lxd/logs/gui64/proxy.X1.log
Status: Started
Warning: Error while sending data: read unix @/tmp/.X11-unix/X1->@: EOF

Warning: Error while sending data: read unix @/tmp/.X11-unix/X1->@: EOF
Warning: Error while sending data: read unix @/tmp/.X11-unix/X1->@: EOF

But I believe it is unrelated as one of those lines gets added every time a GUI program is terminated (e.g., whenever I close xclock) so it’s probably just the socket giving a warning when the connection is terminated.

Can you give me pointers on how to debug the issue further?

Using strace I checked and it seems inside the container everything should be in place, and the “gl-wrapper” is correctly pointing to libnvidia-gl:

So at this point, I am thinking something is weird about the host, maybe permissions?

It looks to me that it is trying to send to the abstract Unix socket of X11.
I do not think I have published yet a tutorial on using the abstract socket. Which guide are you using?

You can try the following LXD profile. Here you do not need to manually install the client libraries for Nvidia; they are automatically provided by LXD by downloading the NVidia runtime. Also, we use a proxy device to share the X11 Unix socket of the host to the container.

$ lxc profile show guinvidia

The one I was troubleshooting was generated using the instructions here up to the glxinfo step, with the difference that the host is 18.04 and not 19.04.

Before I tried also the older posts, defining ad-hoc profiles, ending up with the same situation where basic x11-apps worked but libgl stuff complained.

For the container I was troubleshooting this was the configuration:

Vulkan Instance Version: 1.1.70

Cannot create Vulkan instance.
/build/vulkan-UL09PJ/vulkan-1.1.70+dfsg1/demos/vulkaninfo.c:768: failed with VK_ERROR_INCOMPATIBLE_DRIVER

Vulkan is not available yet in the nvidia container. See this issue and the upstream report,

The upstream report describes how to manually enable Vulkan for now in the container.

Thanks, everything works now.

Also I realized the error in my previous attempts was that the container and the host did not have the same exact version of the nvidia drivers (they were both 430, but different minor version) because in the host I had the graphics-drivers PPA enabled!

Thanks again for the help and for the useful guides!

Hi All!

Simos, first of all thank you for your answers. I also try use GUI app in LXD.
My host worsk on CentOs7 and my lxd also works on CentOS7. And… xclock works fine, but glxgears shows a black window and some errors in terminal:
libGL error: unable to load driver: swrast_dri.so
libGL error: failed to load driver: swrast

I tryed to install nvidea driver in container but failed. Installer disaplay: “An NVIDIA kernel module ‘nvidia-drm’ appears to already be loaded in your kernel…”

Could you help me to figure out ?

Thanks in advance.

Hi!

The error message says that it could not find any GPU GL (acceleration) libraries in the container.

The container needs to get the GPU libraries, and one way to do so, is by installing the full GPU drivers.
Now, depending on the distribution, you might get such an error that the kernel module for the GPU is already installed, because indeed the kernel driver is installed, on the host.
From what you tell me about CentOS, the full GPU package installation fails in the container because it requires to successfully install the whole lot.

There are two ways to bypass this problem.

  1. See https://blog.simos.info/i-am-running-steam-wine-on-ubuntu-19-10-no-32-bit-on-the-host/ which is about Debian/Ubuntu, and shows how to install GPU libraries but not the GPU kernel package. And try to replicate for CentOS (I do not use CentOS).
  2. See this post, GUI Apps in LXD container on how to use the NVidia Runtime in the container. This should become the preferred way. You need to set nvidia.runtime and nvidia.driver.capabilities in the container for this to work.

Hi!

I tryed to implement approach #2. I replaced my gui profile to profile for nvidia and container not started:
lxc start centos7

I want to render with OpenGL in LXD without an X Server in host. what can I do ?

Hi!

I suppose you only need the OpenGL libraries to be available in the container, and have access to the GPU from the container.

To give access to your GPU inside the container, you need to run (from the host) the following. If you have more than one GPU, you may need to add parameters that distinguish one from another.

lxc config device add mycontainer mygpu gpu

If you have an Intel or AMD GPU or Nvidia (nouveau), then you would need to install the corresponding GL libraries (mesa). Sorry, I do not have the proper list handy at the moment.

If you have an NVidia GPU (closed-source driver on the host), it used to be much harder but now it is apparently easier because Nvidia distributes a runtime and LXD can use it. In that case, you can run from the host,

lxc config set mycontainer nvidia.runtime true
lxc restart mycontainer

Can you show what’s in the nvidia profile?

The command is:

lxc profile show nvidia
