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. :)
