If somebody was to create an interface then I'd think something like this in KDE Components/Session Manager, General section:
All of the following are disabled/ghosted when "Confirm logout" is unchecked. When "Confirm logout" is enabled then the following widget is enabled/unghosted.
- A radio button: Enable fancy gray fadeaway
When that radio button is enabled then the following become enabled/unghosted:
- A slider control from zero to 1.0 for darkness
- A slider control from zero to ?? milliseconds for fade
time
- A slider control from zero to ?? milliseconds for restore
time
- If the system is running the Ubuntu OS, then a check box
appears, but only if the OS is Ubuntu.
Oops. I meant check box, not radio button. :)
