On a Macbook Pro 8,1 which should be using bcm5974, I got the same defaults of 70 and 75. Those worked fine for that driver/device. I'm fairly confident that is what is going on here - the defaults were updated for all devices when they should have just been updated for newer devices using the newer driver.
Where do these default values come from, and how can we change them (for all Ubuntu users with Macbooks)? -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to xserver-xorg-input-synaptics in Ubuntu. https://bugs.launchpad.net/bugs/1246215 Title: Ubuntu 13.10, wrong settings for Apple (mouse) touchpad in Macbook 4,1 Status in “xserver-xorg-input-synaptics” package in Ubuntu: Confirmed Bug description: The default settings for the touchpad of a macbook 4,1 in Ubuntu 13.10 render an awkward mouse behaviour that is found during and after installation. The following issues are found: 1) Moving the cursor shows an intermittent behaviour because the parameters for FingerLow and FingerHigh are way too high, hence affecting the sensitivity and requiring more pressure to move the mouse. 2) Having enabled Two-finger tap for right click, using vertical scrolling with two fingers often ends up in a right click. Fixes: I have permanently fixed the settings by editing the first Section block in file "/usr/share/X11/xorg.conf.d/50-synaptics.conf" Section "InputClass" Identifier "touchpad catchall" Driver "synaptics" MatchIsTouchpad "on" # This option is recommend on all Linux systems using evdev, but cannot be # enabled by default. See the following link for details: # http://who-t.blogspot.com/2010/11/how-to-ignore-configuration-errors.html MatchDevicePath "/dev/input/event*" Option "FingerLow" "30" Option "FingerHigh" "40" Option "MaxTapMove" "25" EndSection The added parts are: Option "FingerLow" "30" Option "FingerHigh" "40" Option "MaxTapMove" "25" where FingerLow and FingerHigh fix issue (1), and MaxTapMove fixes issue (2).
