Describe the solution you'd like

It’s a little jarring when you go to shut down the computer, and you see the screen go black with parts of open windows there for a split second.
Maybe a fade to black before the shutdown command is issued could work to add a little bit of polish.

Existing work

Can’t find any alternatives. I know Windows has a fade through black to a shutdown screen then shuts off the display, but you can’t really port that over easily at the moment...

I could try making it myself, but I don’t believe I have enough experience yet to do that with enough finesse.

If this is the wrong place to post the issue, please let me know where a better place would be, and I’ll happily move it over there.

Since the new locker stuff does this, is it just a matter of calling that before shutting down?

@cassidyjames I wanna say the greeter on elementary is running on a different x server like gnome, but I think you’re on the right track.

I also know that gnome has a slow fade to black when falling asleep by itself. I haven’t taken a look at the source, but it could be a compositor thing. Maybe a solution could be taking that and applying it at a faster rate before the shutdown command is issued.

Forget my last reply. I just woke up and didn’t read it completely :).

Yeah. Just calling it before shutdown is what I’m thinking.

Poked David about this during standup and he said we’d need to pull that code out of the screensaver interface so that it could be re-used for shutdown since that’s a different interface

Might also be great if it could be implemented in the sleep button as well.
