I am having the same problem described by Cd-MaN on Ubuntu 14.10. I have three monitors connected to hdmi, vga, and dvi. The center monitor is oriented vertically (rotated 90 degrees).
Occasionally, on the two side monitors (which are conventionally oriented) the mouse pointer will be duplicated and rotated 90 degrees. Moving the mouse into the center (vertical) montor, the pointer goes back to normal, moving it back to the side monitors reproduces the additional rotated pointer. I can usually make this go away by opening a terminal, putting my mouse cursor in the terminal window, and typing exit. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xorg in Ubuntu. https://bugs.launchpad.net/bugs/1071722 Title: Mouse cursor duplicated in dual screen setup To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1071722/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
