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 Bugs, which is subscribed to 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 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
