SDL failed to create window

Trying to setup SDL on a debian system I am getting this error:

INFO: SDL Failed to create window Couldn’t find matching GLX visual

running glxgears from the command line works, I have installed the nvidia
drivers

what could be wrong?

here’s the info output from glxgears

Its possible that hardware acceleration isn’t available, and thus a usable resolution isn’t available.

Also the resolution and/or bit depth isn’t available.
