[Snap 8.0] javax.media.opengl.GLException

Hi all.
I installed version 8.0 of Snap on my laptop with Ubuntu 20.04 LTS, 32 GB of RAM, and at startup I have this error:

javax.media.opengl.GLException: Profiles [GL4bc, GL3bc, GL2, GLES1] not available on device null
	at javax.media.opengl.GLProfile.get(GLProfile.java:949)

I tryed to switch to WorldWind flat mode but without succes. Reading some issue on stackoverflow I intend that maybe there is an incompatibility with JOGL.

Any suggestion?

You should mention your graphics hardware, the linux driver, and whether you use Wayland or X11.

NASA WorldWind used to have extensive installation instructions that dealt with OpenGL issues. The current version targets Java 11. I assume SNAP is using an older version.
In the past I have used JOGL Demos and WorldWind Demos to sort out linux graphics issues independ of SNAP.

Thanks for reply. I’m using X11 and may graphics hardwere is an integrated Intel UHD Graphics 620

I will try with your links, thanks

A couple things that may help with troubleshooting:

  • Does glxgears work?

  • Have you installed the current updates to your linux distro, in particular Mesa?

  • Does the error go away if you use export LIBGL_ALWAYS_SOFTWARE=1 and then
    run snap from the same terminal (so it will see the changed environment)?
