Yes, but I think we are all getting a bit fed up with your questions.
You have installed the xorg-edgers s/w and have to remove it, not just
remove the source.  Go to the xorg-edgers web site and find how to
purge the ppa files and restore the original ubuntu versions.  I
cannot guarantee this is the source of the problem however.

What do you mean when you say 'a fault with your update manager'.  It
does not belong to anyone here, we are just a group of people trying
to help others.  We have tried hard to help you but you have not made
it easy.

To suggest that the xorg ppa got into your system without you doing
anything is ridiculous I believe.  You may not have realised you were
doing it but you must have done something.  Unless someone else has

Also please don't copy me on the email I do not require two copies.  Thanks.
