Reviewing the files from your upgrade attempt you seem to have enabled the xorg-edgers-ppa. This will prevent the upgrade as that PPA contains different versions of packages essential to Ubuntu. The page, https://launchpad.net/~xorg-edgers/+archive/ppa, contains details on to how to revert to the official Xorg packages. Thanks.

Ok. Thank you very much, I could upgrade to 14.04. I installed ppa-purge and then I removed the repository xorg-edgers, then the packages had been revert to the official Xorg packages:

>> sudo apt-get install ppa-purge
>> sudo ppa-purge xorg-edgers
