I just take last few hours to figure out that the problem was on g-s-d, when try to fill a bug report just found this one.
Searching on Google we can see that lots of people try to create a workaround using scripts just to set synaptics option "TapButton3" to "2". Just try to search on Google for "ubuntu synclient TapButton3=2" and you guys can see how much trouble this patch is causing. Tested here and after remove this patch everthing just start to works perfect. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1073369 Title: Ubuntu patch unconditionally breaks three-finger tap To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-settings-daemon/+bug/1073369/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
