How to setup FSAA on Intel Graphics / NUC on Ubuntu?

Anti-aliasing is running perfectly on an application running under Windows 10 on Intel Graphics UHD series embedded in a NUC. But with the same application running under Ubuntu 22.04 and the same hardware, the anti-aliasing doesn’t seem to be available, typically glGetIntegerv GL_SAMPLE_BUFFERS_ARB and/or GL_SAMPLE_BUFFERS return 0 samples.

The main difference is that on Windows, there is a driver configuration application that allows to setup anti-aliasing (enable/disable/let the app choose), but on Linux, it seems that this tool doesn’t exist.

I’ve also tried via the xorg.conf files by following these articles:
1)Intel Graphics Arch Wiki
2)Configuration Details Arch Wiki.
But I didn’t find anything regarding anti-aliasing.

Thanks for any clues!
