Not convinced that the OS is broken because I have had no problem on my system using Aperture pictures reliably as a desktop whether under Lion or previous OS variants. System Preferences>Desktop & Screensaver and Aperture shows up. Click on the triangle and select the folder. Maybe you have to have a folder in Aperture for that to work. Or maybe you need to have Previews created and set to be shared. Apart from these possibilities if there is an issue I suspect that you must look for it in your specific hardware or software setup.

unfortunately i have this problem on all my machines (multiple imacs and a macbook). their configurations are similar, i suppose, but not identical. i do have previews set to be shared (all the time). and aperture does appear correctly sometimes. there are other people here who have reported the same problem.
could it have to do with having a large number of projects (500), or a large apeture file (140G)? (bruce, how large is your apetrue file?)
the problem feels like aperture is locking its previews from being shared, perhaps while it does some sort of updating to its db?

I have 28000 images over 860 Projects references. However since my previous reply I have ascertained that while I can use a single Aperture image as the desktop it doesn't work if I want folder or Project images to rotate. I found the way to do that was to export the images into a reguar folder on the Hard drive and then select that.

I have exactly the same issue as markmal. It started about the same time as my H D started making scratchy nioses which apple store genius and I agree is very bad.

I recall having a similar problem with iPhoto actually, long ago before I got Aperture, and the solution was to delete the plist file that tracked which wallpaper folders you'd used before, your iPhoto and Aperture libraries, etc.
Letting OS X (or Finder?) rebuild the plist file resolved the issue completely at the time.
I believe the file is called "com.apple.desktop.plist".
If you venture this way, you might find you'll have to re-open and close Aperture to let it re-publish itself into the plist file before you'll see your projects appear again.
Hope this helps!

Just wanted to pop in and said I've been dealing with this issue on my MBP for months now... the only suggestion that EVER worked was Francois's one.
Thanks so much buddy!

i've tried this several times to no avail. deleting the plist file doesn't seem to change anything. the desktop images work for a while (usually hours, through several sleeps), then the "connection" is lost again.
