Could not initialize GLX with NVIDIA 384.66 on Ubuntu 16.04

Graphics / Linux Linux
#1

Hi,

I’m running ubuntu 16.04 with three Titan X cards. I installed NVIDIA 384.66 driver as part of installing cuda via the following commands:

sudo dpkg -i cuda-repo-ubuntu1604_8.0.61-1_amd64.deb
sudo apt-get update
sudo apt-get install cuda

I also followed the steps listed in this StackExchange answer: https://askubuntu.com/a/457928/439653.

However, when I run an X-Window application that uses GLX (Agisoft Photoscan, to be precise), I see the following output:

Could not initialize GLX

Additionally, when I run glxgears, I see:

Error: couldn't get an RGB, Double-buffered visual

(In both cases, the program crashes.)

The above problems also occur with 3 1080Tis in another machine.

Can someone help me fix this? Thanks.

Looks like you don’t have a monitor connected and use AllowEmptyInitialConfiguration to get the xserver started. This way, you don’t really get a (virtual) screen. Use option ConnectedMonitor to achieve that.

#3

You should still get GLX even with AllowEmptyInitialConfiguration. From the attached bug report, it looks like libglx is initializing correctly in the X server. Can you please attach the output of glxinfo from one of the X screens? Also please check that the correct client-side libGL is installed. The bug report script normally uses “ldd /usr/bin/glxinfo” to check this, but apparently you don’t have glxinfo installed.

Are you trying to use indirect GLX, by any chance?

Here are some key outputs:

Perhaps I am trying indirect GLX? I’m not sure what that is. I’m running SSH -Y from a remote client. Is that the problem?

Hello,

Please provide me the solution if someone has the resolution.

If you want a simple solution, set up a real X server then use x11vnc to connect.

#7

@williamvdk: Try export __GLX_VENDOR_LIBRARY_NAME=nvidia before you start your program with indirect GLX.
