GNOME Display Manager (logon screen) and Screensaver:
I wrote quite a significant comment on this in some Ubuntu Wiki pages, but it seems like they are going for crazy 3D-ness (nothing against you Mirco, loads of people have said how cool the Cairo Clock on my desktop is ;-) ). I wanted to test this idea for myself, and Warbuntu would be a great place to do it. Here's the basic idea; the GNOME logon screen doesn't really fit in with the desktop when it is in "themed" mode, but the non-themed mode looks ugly. Also, there are far too many ways to switch user, and I think locking a session shouldn't be appear any different to other system users than if you've logged out. So here it is, my quickly done Gazpacho mock-up for the login screen:
Here nobody is logged in (although that shouldn't make a difference). The GTK theme is just the one I made/use by the way so this should be made customisable with a default theme. The text at the top is the system message (currently the default is usually "Welcome to [hostname]
So there you have it
Please leave any thoughts and remember that this is a little experiment of mine, and not directly intended to replace the current system, just to encourage more out-of-the-box thinking (ewww... I just said "out-of-the-box thinking"). Also, if Canonical want to give me their UI job then I would be damn pleased :D http://www.ubuntu.com/employment
Update: I thought I may as well link to some other user interface things I might put in Warbuntu. First there is my Usplash proposal: https://wiki.ubuntu.com/Usplash/EdgyPropositions (at the bottom), then there is my idea for an APT "Service Pack" maker, ie. an easy way of installing loads of Debian packages at once (personally I think my idea [scroll down] is easier to implement, easier to use and more powerful than the main one being discussed in that page, and this may be the first one of my mockups to come to fruition). I might add some more if I can remember them :) Oh, and a big thank you to Steve Jobs for the EMI non-DRM thing. I might pay some people to get me some non-DRM songs from iTunes for me, to show my support (also, I assume they expertly tweak their encoders to get much better quality than I could hope for with Grip since I just press "Go" :-) )
Another Update: I also have the GNOME preferences thing to work on that I comment on here. Toodle pip.
