Adriano, thank you for reporting this and helping make Ubuntu better. As per https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1510157 you are using the fglrx software you installed a few days ago.
Hence, if you want to use the open source drivers, you would need to uninstall the fglrx software. As this is not a software bug, but a technical support issue, this report is being closed.
