I recently switched away from sgfxi after the resulting driver was unable to run OpenGL applications and installed the packaged Debian Experimental (387.x) drivers instead. Unfortunately, they are showing the exact same error as the sgfxi one (I think): Most applications at least complain about missing / bad OpenGL, and many refuse to start. In its most verbose form, it looks like this:
name of display: :0
libGL error: No matching fbConfigs or visuals found
libGL error: failed to load driver: swrast
X Error of failed request: GLXBadContext
Major opcode of failed request: 154 (GLX)
Minor opcode of failed request: 6 (X_GLXIsDirect)
Serial number of failed request: 48
Current serial number in output stream: 47
That is the (only) output from glxinfo and other such utilities. Most other applications only have the two lines starting with libGL, some also something like "Unrecognized OpenGL version".
Now, Googling quickly results in the conclusion that this is because I'm using the wrong libGL.so.1. Unfortunately, I don't really know how the graphics system works, so all I can do is provide you with a wide context and hope someone figures it out or asks the right questions.

apt-file search libGL.so.1 tells me that there are only two possibly relevant packages (if this is the right path at all), but libgl1-glvnd-nvidia-glx conflicts with libgl1 on which a lot of applications depend and libgl1-nvidia-glx is a legacy version from Oldstable.
Does anyone have the divination skills to tell me what the problem is?
