slicer can't find latest OpenGL drivers in AWS workspaces

Support
1

Operating system: Linux (AWS workspaces Power Pro x86_64)
Slicer version: 4.10.2
Expected behavior: Display dicom images
Actual behavior: Error message about not finding latest OpenGL drivers despite those being present on the system.

Unable to find OpenGL 3.2
However, on the terminal when I do:

glxinfo | grep OpenGL
I get core profile and version string as 3.3
I do get ES profile version string as OpenGL ES 2.0 Mesa 18.3.4

Not sure how to make slicer find the latest version of OpenGL

Help appreciated.

Let me know if I can provide any more details. Right now the dicom images load but do not show up (are not seen).

Thanks!

Do other OpenGL applications work, such as glxgears test?
Please also try with latest Slicer Preview Release.

I’ve run Slicer on AWS Workspace with Windows and it works fine, with GPU support.

GPU OpenGL on Linux is always tricky, so maybe Workspaces doesn’t provide the right hooks.

If Google Cloud is an option for you, these instructions work well for me.

Probably the same approach would work fine with EC2 as well.

Will try that. Thanks for pointing it out. I was not aware of it. (Though it may end up being unconnected with the slicer part).

Thank you, Steve. Google cloud or using a windows machine is not an option in this case as there are a lot of other projects that use this configuration.

What OS do you use on AWS Workspaces? There’s a good change standard drivers will work, so long as you configure them right.
