Thank you for taking the time to report this bug and helping to make Ubuntu better. I'm assigning this provisionally to the Linux kernel, since it looks like your kernel fails to recognize the pointing device.
I'd like to ask you for some more information to better assess the problem. Please run the following command which will attach necessary information: apport-collect 799938 Also, please post (as a comment) the output of running xinput --list in a terminal window (press ctrl-alt-t to open a terminal). For your reference, the full description of procedures for kernel- related bug reports is available at https://wiki.ubuntu.com/KernelTeam/KernelTeamBugPolicies.
