Hi, I'm trying to get OpenGL 3d graphics support for my Dell Latitude D810, which has a Graphics card that is no longer supported by "conventional" drivers. That said, it is crucial for me to get drivers that DO work, and the ones I've found are not updating properly.

as far as I can tell, the launchpad ppa either isn't added to my software sources, or it isn't there at all. I ran the following in a terminal. Please let me know if I'm posting in the right place or if I can get any help here. In any event, Thank you for your assistance.
