** Description changed:

  Binary package hint: xorg
  
  I logged in with GDM, and pressed ctrl-alt-F1 to access a text console
  (which was successful). When I tried to switch VT back to the X session
  I saw the screen flicker and after a few seconds the GDM login screen
  appeared. The X session was lost.
  
  What I expected: to be able to switch back from the text console to the
  X session.
  
  What happened instead: the X session was finished and I had to log in
  again.
  
  The last few lines from Xorg.0.log were:
  
  (II) AIGLX: Suspending AIGLX clients for VT switch
  (II) Open ACPI successful (/var/run/acpid.socket)
  (II) AIGLX: Resuming AIGLX clients after VT switch
  (II) intel(0): No memory allocations
  Fatal server error:
  Failed to submit batchbuffer: Bad file descriptor
  
  This is Lucid 10.04 with all updates as of today (6 May 2010). The
  xserver-xorg and xorg packages are 1:7.5+5ubuntu1.
  
  From Xorg.0.log.old:

  (II) AIGLX: Resuming AIGLX clients after VT switch
