Be more specific. The Xorg log does not show any issues (other than the fact that you're using a third-party driver from oibaf's PPA that isn't supported by a bug report on this site...).
We have instructions on debugging some types of problems at https://wiki.ubuntu.com/X/Debugging At a minimum, we need: 1. the specific steps or actions you took that caused you to encounter the problem, 2. the behavior you expected, and 3. the behavior you actually encountered (in as much detail as possible).
