I think I have found a way around this bug. It's not pretty, and I must give credit for the idea to Nicolas Caval, the person who reported the same bug on the Debian bug tracker. He found a way around the bug for his needs, but it didn't work for me. Here's what I did to make it work:
1. apt-get source xserver-xorg-input-synaptics 2. sudo apt-get build-dep xserver-xorg-input-synaptics 3. cd xserver-xorg-input-synaptics* 4. gedit synaptics.c 5. go to line 1610, where you'll find: int timeleft; int i; /* update hardware state in shared memory */ para->x = hw->x; para->y = hw->y; para->z = hw->z; 6. insert the following code right between the two blocks of code, so it looks like this: int timeleft; int i; /* this is crap, but it saves the day */ if (hw->x == 1 && hw->y == 5855) { hw->numFingers = 0; hw->fingerWidth = 0; hw->z = 0; hw->x = HIST(0).x; hw->y = HIST(0).y; } /* update hardware state in shared memory */ para->x = hw->x; para->y = hw->y; para->z = hw->z; 7. save & close the file 8. sudo dpkg-buildpackage 9. cd .. 10. sudo dpkg -i xserver-xorg-input-synaptics*.deb 11. restart X with CTRL+ALT+Backspace ** Changed in: xserver-xorg-input-synaptics (Ubuntu) Status: Confirmed => Fix Committed -- Synaptic touchpad fails to register some of the taps for tap-to-click https://bugs.launchpad.net/bugs/133060 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
