Regarding the OP, at least the Intel and Mesa is still supported. My information says that Ubuntu is dropping ATI for lack of any kind of compatibility support or something like that. The 386 processer is being dropped. I can see a deer in my headlights that has a CD-ROM on his forehead. It just a matter of what hardware will use RR and that hardware will most likely have a DVD or BlueRay and most certainly a USB.
Life is good! Live it to the Ubuntu-ist! Until Friday!
