ok, after further googling it turned out these up-right and bottom-right top shortcuts for middle and right button are default in Ubuntu (and not specific of our trackpad). So the new driver is working as expected.
For those finding very annoying the accidental middle button click when tapping the up-right part of the trackpad there is a workaround to disable it using the synclient command: synclient RTCornerButton=0 ! disable up-right middle click synclient RBCornerButton=0 ! disable bottom-right right click You can also put the above commands in the "startup applications preferences" control panel to make them persistent after a reboot -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1590590 Title: Touchpad not recognized on Dell Latitude E7470 Ultrabook To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1590590/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
