I hope this doesn't necro this thread. But I can add some information around this bug, and possible fixes for those plagued by it.
I had this problem, and it developed after accidentally deleting my home directory, and rebuilding it piecemeal from an old backup (so it may be configuration related), and after trying to install ATI proprietary drivers through kubuntu's driver manager. The specific conditions where the mouse cursor would show up on the primary monitor was: when I moved the mouse to the secondary monitor, the cursor would show up at the same horizontal position that the crossover happened once the mouse cursor changed icons (vertical position was dependant on the speed the mouse was moving when it changed screens). The ghost cursor would then stay on the primary screen and would mimic the mouse icon, until the mouse was moved back to primary. My fix seemed to be to remove proprietary drivers and reinstall open source drivers. I also needed to force install a dependency for the open source drivers. sudo apt-get remove fglrx* sudo apt-get install xserver-xorg-video-ati sudo apt-get install xorg-video-abi-15 sudo apt-get install xserver-xorg-video-ati Hope this helps anyone looking for answers. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to xorg in Ubuntu. https://bugs.launchpad.net/bugs/1071722 Title: Mouse cursor duplicated in dual screen setup Status in xorg package in Ubuntu: Expired Bug description: I have attached a external monitor to my laptop. When I my the mouse from the primary display (my laptop screen) to the secondary display (external monitor), the mouse cursor image gets duplicated. On the primary screen it freezes its last location (so moving the mouse more quickly, makes sure that the mouse image is clearly visible) and on the secondary screen it keeps on performing as it should. When I move the mouse back to the primary screen, the duplicated mouse image disappears and everything works like normal again. When the duplication is 'active' the frozen mouse, still changes it's image (pointing finger, 'text thingy', resizing arrows, etc.) when my mouse on the secondary screen is hovering over elements that makes the image change. Since Ubuntu 12.10 I use the xserver-xorg-video-radeon package, as fglrx does not support my ATI video card (HD 3650) anymore. So I do not know whether the problem is also existing pre-12.10. This is not reproducible in the live environment of 13.10 and 14.04, but is in the installed ones.
