** Description changed:

- Generic bug so I remember to investigate this. Apparently on some
- systems the fallback doesn't happen as it should and people get an empty
- session instead of unity-2d.
+ [rationale]
+ DESKTOP_SESSION isn't properly set when using the "default" session (no parameter passed to Xsession), this leads to gconf not loading the custom unity settings, resulting in just nautilus being running.
  
- Manually selecting unity-2d works around the issue. I'll release note
- this bug and investigate when I get back home.
+ The fix adds an Xsession.d script to both ltsp-client-core and ltsp-
+ server, this script parses the parameter of Xsession and sets
+ DESKTOP_SESSION to the expected value, similar to what lightdm does on a
+ regular desktop.
+ 
+ [test case]
+ 1) Build a fat client chroot on a working LTSP system (ltsp-build-client --fat-client)
+ 2) Boot a 3D capable thin client
+ 3) Login using the default session
+ 
+ 3) in the past would lead to a blank screen, with the fix, you get
+ unity-3d.
+ 
+ [regression potential]
+ As far as I can tell, DESKTOP_SESSION is only used by gconf at the moment, so if the code fails, all we should get is more gconf weirdness, though I can hardly see how it could get any worse than not getting a desktop session.

Title:
  Unity doesn't start at all on a 3D capable machine instead of falling
  back to unity-2d as it should (because of lack of 16bit support in
  compiz).
