Upon downgrading back to Ubuntu 10.10 after my horrendously bad experience with 11.04, I’ve been reunited with a bug I’d previously put up with for 6 months: The trackpad on my laptop often ‘mouseups’ when dragging, resulting in windows not being dragged correctly. In addition, web browser and pidgin tabs will occasionally close on click instead of giving focus to that tab. Well here’s the fix!

Make sure the following 2 lines are In the InputClass section of /etc/X11/xorg.conf.d/50-synaptics.conf:

Option "ClickFinger3" "1"
        Option "EmulateTwoFingerMinZ" "280"

Here’s what mine looks like:

Section "InputClass"
        Identifier "touchpad catchall"
        Driver "synaptics"
        MatchIsTouchpad "on"
        MatchDevicePath "/dev/input/event*"
        Option "ClickFinger3" "1"
        Option "EmulateTwoFingerMinZ" "280"
EndSection

You’ll probably need to do a reboot for the changes to take effect.

Thanks to users egermani and ejmarkow for their respective fixes here and here.
