Thanks for your suggestions. I have ruled out hardware. I did change a BIOS 
setting to make the function keys be functions without the fn key (this is a 
Dell laptop). The only other thing I changed was to run a script to record the 
time and some of the hw.acpi sysctl values. As I now have the upgrade installed 
I will try the buildworld again. The screen does go into standby and I am not 
sure what is controling that, nothing in KDE or Xorg that I set, perhaps a 
sysctl setting but I did not see one in the acpi section.
