As I don't really know what the cause of the problem is, all the information that I can give is that I installed the updates that were given. Prior to this the graphics were working properly. I can only access a single screen size and if I try to change it I am told that Full Screen is not available in this profile which is marked at present, nvida. if I try to initiate another profile I either get the same message or that profile is not available. I am sorry that I can give you no further information but this is all I know.
