Jim,
Thanks for the suggestions. I think you hit the nail on the head with the nvidia card. X runs great with no obvious problems. I only need to get one more app runing and it is for ham radio. I am trying to compile a app called soundmodem. It interfaces the computer with a ham radio for packet operations. When I compile it I get errors telling me xml is not available. In my search for xml I have found that xml is replaced with xml2. I tried changing the source calls for xml with xml12 but it failed with modules not being present, and none of the names that it was looking for were not system modules. But I will get it going somehow. The app will be used by Emergency Services in the county where I live. Thanks for your help on the X problem.
Dick
