As mentioned there, I have the same problem in Utopic AMD64 with MATE 1.8.1; this began immediately on my upgrade from Trusty to Utopic and continues to the present. I have a double mouse pointer appear intermittently during web browsing (Firefos 35.0.1), often when click-dragging a link to open in new tab, and then it persists. Although two pointers are visible only the left pointer is active. If I log out and back in, the single mouse pointer is restored.
This is a Lenovo IdeaPad Y510P with the latest BIOS, and I am fully updated on Utopic AMD64 with no broken packages etc.
This appears to potentially be the same bug as https:/ /bugs.launchpad .net/ubuntu/ +source/ xorg/+bug/ 1393169.
