Re: Screen Saver & Screen Lock in CDE not works
The Reflection/X runs on Windows environment, which already has its own screen saver/screen lock functions.
Thus, Reflection/X does not have complete control of the screen and keyboard, but must share them with Windows. This means the user could always override the lock by manipulating Reflection/X locally. So it might be a design choice that the Reflection/X reports to the remote X applications that it has no screen saver and/or screen lock capability, since such a lock would not be reliable anyway.
(Remember that an X session is more of a collection of applications that each communicate separately with the X server. A typical screen locker implementation just tells the X server to "grab" the keyboard and mouse focus so that other X applications won't receive it until the locker program receives the correct input to unlock the screen. Some X servers have a way to forcefully remove any existing "grabs". On Unix hosts, such removal would typically require root privileges. But Reflection/X is an X server that is completely under the control of the Windows user that started it, so it would make the screen lock rather meaningless.)
