May 22 15:13:50 <NekoXP> hey guys. anyone know where in gdm or standard gnome desktop session stuff the backgrounds are handled, like when you swap backdrop it does that fade between backdrops?
May 22 15:14:43 <OurMaNdO|W> compiz
May 22 15:15:11 <OurMaNdO|W> compizconfig settings manager
May 22 15:15:15 <OurMaNdO|W> under animations
May 22 15:15:20 <OurMaNdO|W> will allow u to change
May 22 15:17:06 <NekoXP> this is pre-compiz.. like maverick/oneiric kind of era. I assume gnome-session is handling the background transitions, but it seems unlikely (or maybe it is very likely) that gdm wouldn't share this code (since it does the same thing logged in and for loading the gdm splash)
May 22 15:17:30 <OurMaNdO|W> i was using compiz with 10.04
May 22 15:18:26 <OurMaNdO|W> which was before maverick and oneiric
May 22 15:18:32 <OurMaNdO|W> i also use it on 13.04
May 22 15:19:15 <NekoXP> hmm window manager is a good place to look, I guess gdm needs one too and that makes sense.. so it'd be metacity
May 22 15:20:47 <OurMaNdO|W> window manager doesnt handle window animations
May 22 15:20:56 <OurMaNdO|W> a fade is an animation
May 22 15:21:16 <OurMaNdO|W> opengl and compiz handle it
May 22 15:23:49 <NekoXP> okay you're just not helping at all.
May 22 15:25:20 <NekoXP> I have metacity and gdm. I updated cairo for a good reason, and now my fade-between-backgrounds on gdm and inside gnome using the gnome appearance properties has turned from a fade into a kind of burn-in effect (everything scales to white). I am looking for the thing that handles that fade effect *for the background image* on the root window.
May 22 15:28:59 <NekoXP> it would probably be also called from anything that uses the xml backdrop stuff, since every transition does the same, it should be the new backdrop going from full transparency to full opacity over the current background, but it instead does what in Photoshop is the multiply filter, then snaps to the new image. So I assume it's some kind of alpha channel pre-multiplication thing or the values are backwards or.. I can't figure out what is even
May 22 15:28:59 <NekoXP> handling rendering the backdrop let alone find code
May 22 15:39:33 <NekoXP> there's got to be something that's watching for gconf updates in desktop/gnome/background and then doing the rendering.. if I knew that I'd know what it told to go render it if it didn't do it itself..
May 22 15:41:44 <NekoXP> bang. it's gnome-settings-daemon
May 22 15:43:27 <NekoXP> which calls libgnomeui...
May 22 20:18:36 <mfisch> ogra_: you still around?
