** Description changed:

  Binary package hint: x11-common
  
  Some background:
  I am working on the Mesa Radeon driver. When testing out Git-based X.Org and Mesa, I keep self-compiled things in their own prefix (contained in my home directory) because I want to keep Ubuntu-supplied packages clean. To test things, I shutdown GDM and start X manually. However, I want to keep as much of the default Ubuntu *client* aspects the default, so I start via xinit (passing a sudo-wrapper for the X server and setting environment variables as appropriate).
  
  In particular, I need to set LD_LIBRARY_PATH, as otherwise clients will
  not find the right libGL.so.
  
  Expected behaviour would be that the environment with which I call xinit
  is the environment that clients in the session will see.
  
  However, this is not the case, because ssh-agent (which is setuid) is
  indirectly a parent of all clients.
  
  I worked around this by adding a small script to /etc/X11/Xsession.d, which essentially is just:
    STARTUP="/usr/bin/env LD_LIBRARY_PATH=${LD_LIBRARY_PATH} ${STARTUP}"
  before the script that adds the ssh-agent (I guess it would make more sense to put this into the script that adds the ssh-agent to $STARTUP, but I didn't want to change any files installed by packages).
  
  I realize that I'm as fringe a usecase as you can be, but since this is
  *really* surprising behaviour, took me about two hours to figure out
  (just digging to what happens at X session startup takes a long time if
  you've never done it), and is quite simple to fix,so I'd appreciate it
  if you considered fixing this.
