It seems this is a wish, that lives for a long time. In Bug #116919 additional approaches are listed to disable the touchpad, when plugging a mouse.
For my Lenovo x121e the udev rule, provided by Bug #116919 does not work out of the box and I did not find the problem, yet. But for sure it would be great, if a "disable touchpad, when usb mouse is plugged" option would exist. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-input-synaptics in Ubuntu. https://bugs.launchpad.net/bugs/870475 Title: Disable touchpad when plugging in mouse To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-input-synaptics/+bug/870475/+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
