Ubuntu X config

From [1]:

  Your login script, .xinitrc, works with startx, but graphical login
  managers like GDM do not look for .xinitrc. Instead, they look for a
  file named .xsession in your home directory. To make GDM run your
  .xinitrc script, you have to link it to .xsession [...]

Actually that doesn't work any more under lightdm.  See here[2].
