Hi Robie, thanks for you answer, I've asked to the sysadmin to make a test and let me know if X server works fine and he told me that he hasn't verified any kind of issue, so I think that is something wrong with my Ubuntu installation. I've made also a test with a virtual installation(Oracle VirtualBox) of Ubuntu 15.04 and I have the same issue. If this bug/issue will be assigned to an X server developer I'd like to collect any other info about this strange behavior.
