** Description changed:

  I am using the nvidia-glx drivers
  under a ubuntu hardy heron alpha 5 release
  for my Nvidia graphics card (nVidia Corporation G72M [Quadro NVS 110M/GeForce Go 7300])
  in a dell lattitude d620 laptop
  with the driver "nv" set in the /etc/X11/Xorg.conf file for the device module. this works, but of couse without any desktop efffects.
  
  Changing this driver option (as switching from the nvidia-glx driver to
  the nvidia-glx-new driver) from "nv" to "nvidia" to get the 3d desktop
  effects, the login window appears correctly, bu after login, the opening
  of a GDM session fails where the Xserver crashes and restarts after a
  while.
  
  while everything worked well under ubuntu gutsy gibbon with the driver
  option "nvidia" and the 3d desktop effects, I get the reported error
  when using it for hardy heron alpha 5.
