After I upgraded to 12.04 LTS my middle mouse button stopped working... it worked fine before the upgrade. I can scroll with the wheel but when i push it down it refuses to work. Can someone tell me how to make my mouse work again?

    For me (14.04) it worked initially, but since yesterday it just stopped working.

The same issue persists with Ubuntu 17.10 and Xubuntu 17.
