It's a feature.
You're going to have to disable the screensaver.
You're seeing a classic symptom from various laptop systems.
When the screensaver kicks in, the rest of the system goes into a state comparable to a S1 level hibernation.
That halts most all other processes or applications that might be running.
The act of switching back, out of the screensaver, establishes the connections again.
Your Sun system is interpreting it as the same as an abrupt physical disconnect/re-connect of the cable.
Review the man pages for kbd_, although I don't think you can effect any usable changes while in the middle of the installation.
