SFML 2.0/Ubuntu 12.04

[tanmanknex]

There is something that went seriously wrong when I upgraded to Ubuntu 12.04.  I had a perfectly working installation before the upgrade, but now whenever I try and run my project, it opens up a random looking window.  In the console log it shows this over and over:
nvfx_screen_get_param: 95 -  Warning: unknown PIPE_CAP [number]
with different numbers in place of [number]. 
What's wrong and how can I fix it?  I haven't been able to find anything on it through my usual sources (google, yahoo, etc.).

You can check if it's a driver problem by trying to run other OpenGL apps.

It turns out it was an OpenGL problem and installing a new driver fixed it.  I don't know why that didn't cross my mind but I'm glad it crossed yours.  Thank you so much!
