How can i deal with 'libGL error: failed to load driver: swrast.'

[lfwin]

I am using a xrdp remote connecting to a Ubuntu14.04 desktop machine, which successfully installed tensorflow and caffe.
After i install gym and run
import gym env = gym.make('CartPole-v0') env.reset() for _ in range(1000): env.render() env.step(env.action_space.sample()) # take a random action

libGL error occurs.
using "LIBGL_DEBUG=verbose glxgears" , it outputs:
libGL: screen 0 does not appear to be DRI3 capable libGL: OpenDriver: trying /usr/lib/x86_64-linux-gnu/dri/tls/swrast_dri.so libGL: OpenDriver: trying /usr/lib/x86_64-linux-gnu/dri/swrast_dri.so libGL: driver does not expose __driDriverGetExtensions_swrast(): /usr/lib/x86_64-linux-gnu/dri/swrast_dri.so: undefined symbol: __driDriverGetExtensions_swrast libGL: Can't open configuration file /home/lfwin/.drirc: No such file or directory. libGL: Can't open configuration file /home/lfwin/.drirc: No such file or directory. 3751 frames in 5.0 seconds = 750.148 FPS 4278 frames in 5.0 seconds = 855.515 FPS

I googled, but need reinstall nvidia drivers.

EDIT: After i update nvidia drivers, it works in local Ubuntu14.04 desktop machine, but still have error in remote connection

Can you give more detail on what the current problem is?

Hi, @tlbtlbtlb
Now, the problem is when running following code in eclipse in a remote desktop connection using xrdp which connecting to a Ubuntu 14.04 server computer,
import pdb import gym env = gym.make('CartPole-v0') env.reset() for _ in range(1000): env.render() env.step(env.action_space.sample()) # take a random action print("success")
this error below happens:
"

if I run above code using shell, it runs well and display:
"

success
success
...
"
but not display animation.
but if i run locally on the ubuntu14.04 computer, all goes right.
I want to run on remote windows computer.

You need the swrast driver installed for OpenGL rendering to work in headless mode. Typically, apt-get intall -y mesa-utils and libgl1-mesa-glx will do it. But if you have proprietary video drivers installed, it may take some googling to find the answer.

Hi,
I run test LIBGL_DEBUG=verbose glxinfo|grep renderer, it outputs
PowerEdge-R730:~$ LIBGL_DEBUG=verbose glxinfo|grep renderer
libGL: OpenDriver: trying /usr/lib/x86_64-linux-gnu/dri/tls/swrast_dri.so
libGL: OpenDriver: trying /usr/lib/x86_64-linux-gnu/dri/swrast_dri.so

libGL: Can't open configuration file /home/lfwin/.drirc: No such file or directory.
libGL: Can't open configuration file /home/lfwin/.drirc: No such file or directory.
libGL error: failed to load driver: swrast

and swarast_dri.so can be find as follows.
PowerEdge-R730:~$ locate swrast_dri.so
/usr/lib/i386-linux-gnu/dri/swrast_dri.so
/usr/lib/x86_64-linux-gnu/dri/swrast_dri.so

Also, video drivers, mesa-utils and libgl1-mesa-glx all upgraded.

It's a common problem with Ubuntu 14.04 and nVidia drivers. Easy solutions are to uninstall the nvidia drivers, or upgrade to Ubuntu 16.04. Many other solutions at https://encrypted.google.com/search?hl=en&q=driver%20does%20not%20expose%20__driDriverGetExtensions_swrast

[frankcarey]

Note: I fixed this by using nvidia-docker instead

[allenyllee]

Based on the dockerfile of nvidia/cuda, I can solve this problem.
https://gitlab.com/nvidia/cuda/blob/ubuntu16.04/8.0/runtime/Dockerfile

Or you can just use it with nvidia-docker to create another container run all the stuff without touching your OS environments.

[ruapotato]

Wait so I'm seeing this in a basic chroot (drivers installed on the host and chroot.. trying to load steam)
what part of the Nvidia docker is fixing this? I don't want to use docker but I want 3d drivers.

Thanks BuhuanJin, this solved a lot of problems.

[itayave]

I deal with it in Redhat-8.2 (aarch64) with installing the mesa driver:

sudo dnf install -y mesa-dri-drivers

[rohanjuneja]

I am receiving a similar issue, and it did't get resolved even after updating mesa drivers. Kindly could you please help me with this?

For future reference, you can run your programs with the prefix LIBGL_DEBUG=verbose to get debug output.
See https://askubuntu.com/a/566522

yum install -y mesa-libGLw-devel.x86_64 # not work

yum install -y mesa-dri-drivers # worked for me

commmenting for posterity only to help anyone who lands here

For me, I was working on an old ubuntu 14.04 box, after a motherboard replacement and much messing around with the graphics drivers, which for me were old mesa drivers.

I got out my old backup archive HD for this machine and it had a different libGL.so.0.1.2.0 for me to try, in /usr/lib/fglrx

pointing my system /usr/lib/libGL.so and /usr/lib/libGL.so.1 files in a symlink to this /usr/lib/fglrx/libGLS.so.0.1.2.0 worked for me to restore headless libGL working again on this old machine. So if you are getting this error it means you are likely using the wrong version of libGL.so for your machine to load the swrast libs.

yeah, thanks. You help me a lot.
