Starting anaconda-navigator under Xubuntu 24.04 give me the following error:

~$ anaconda-navigator 
2025-05-07 11:16:04,573 - WARNING linux_scaling.get_scaling_factor_using_dbus:32
An exception occurred during fetching list of system display settings.

qt.glx: qglx_findConfig: Failed to finding matching FBConfig for QSurfaceFormat(version 2.0, options QFlags<QSurfaceFormat::FormatOption>(), depthBufferSize -1, redBufferSize 1, greenBufferSize 1, blueBufferSize 1, alphaBufferSize -1, stencilBufferSize -1, samples -1, swapBehavior QSurfaceFormat::SingleBuffer, swapInterval 1, colorSpace QSurfaceFormat::DefaultColorSpace, profile  QSurfaceFormat::NoProfile)

Could not initialize GLX

anaconda-navigator does not start.

With the environment variable export QT_XCB_GL_INTEGRATION=none it works with the following output:

~$ anaconda-navigator 
2025-05-07 11:20:04,677 - WARNING linux_scaling.get_scaling_factor_using_dbus:32
An exception occurred during fetching list of system display settings.

QXcbIntegration: Cannot create platform OpenGL context, neither GLX nor EGL are enabled

...but it is running :)

If I make the environment variable persistent in my .profile, Calibre's ebook reader does not work.
