Bug#803667: upgrade-reports: No Xorg: "no screens found(EE)"

[Ray Andrews]

I fixed it by installing 'nvidea-xconfig' but although my video worked, 
my mouse was dead.  Googling I found I had to add:

Section "ServerFlags"
  Option "AllowEmptyInput" "False"
  Option "AutoAddDevices" "False"
EndSection
to 'xorg.conf', and it all seems fine.  So it seems there's some issue 
with nouveau, and it would be polite if 'nvidea-xconfig' refrained from 
killing the mouse.  Other than that, I don't care which video driver is 
used, so long as the damned thing works.
