Can't run Harrison AVA plugins

Hello, fist I’m sorry because my english is very bad!

I try to install a 5 AVAs Bundle on a 2nd computer (laptop) on linux (Debian). I’ve run the and it just show me the EULA Licencse Agreement. Then I’ve copied the .so files to my vst folder.

When I try to use the plugins, (on Mixbus 6.2.407) I just see a grey window with nothing else…

On my first computer (Ubuntu 20.04), it runs with no problem…

Can you help me?

Thanks a lot.

The plugins require a recent version of openGL. You could perhaps try software emulation
by setting the environment variable: MESA_GL_VERSION_OVERRIDE=4.5

start Mixbus like


Wow! It works perfectly! Even with my Ardour6.6. Thank you so much Robin.
But I don’t understand why it runs on my Xubuntu 20.04 with the same version (but Nvidia instead of Mesa on the laptop…)
Can I solve the problem by installing a more recent openGL package?

The NVIDIA binary driver installs its own OpenGL library.
It’s probably a higher version than the Mesa one in your Debian distro.

If you can find a newer OpenGL version for your version of Debian it should make the workaround unnecessary.
You can check the OGL versions by running
glxinfo | grep "OpenGL version"

OK. Thanks again! I’ll try to find the newer version.
