I am not clear on what you want to do: Use the LUKS passphrase also for the Gnome screen-locker? If so, set one of the keyslots to the passphrase of the screen-locker. If you actually want to remove the LUKS mapping (i.e. "close" the LUKS container) when the screen safer engages and remap the LUKS container when the screensaver is unlocked, then this is complicated. It mau also not be what you want, given that unmapping the LUKS container with open files is eiter not possible or can result in arbitrary data corruption (I have not tried it). So you would need to do something like this on screenlocker-engage: 1. Determine all open files in the LUKS container 2. Terminate all applications that have these files open 3. Unmount the LUKS container and verify it did unmount. If unmount fails, go to 1. (An application could have opened a file in between...) Maybe you can also do a ro remount first. 4. Unmap the LUKS container. Now, this would need to be somehow script-driven from the screensaver. Whether automated application clsoe is a good idea depends very much on the situation and is generally _not_ a good idea.
