Description of problem:
Good Day . . .
While using for instance, a word processor, my monitor, a Sony
Multiscan 400PS, will power down and revert to searching for an input.
The monitor will accept two types of input HD15 and BNC. It will stay
in this state for about 2 to 3 seconds then power up but it will not
display anything just a dark screen.
After power up I must move the mouse or press a key for the monitor to
resume normal activity.
This does not happen during a period of inactivity although it may. It
happens while I am doing something on the keyboard.
It happens randomly with no noticeable frequency other than once or
maybe twice a day.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Too random to reproduce
2. I cannot proceed until I populate the above box
If I were to guess then I would say that it has something to do with
the power management system since I have another issue with powering
down the computer, issue 138781.
The two may or may not be related.
Standby after: is disabled. Suspend afer: is set to 30 minutes. Power
