I've talked about my laptop's touchpad elsewhere...
Given its touchpad position and configuration you trigger the secondary and terciary click while typing as they are bound to the Left Top and Left Bottom corner*.
I know how to fix this(** , ***), I have this:
# Example xorg.conf.d snippet that assigns the touchpad driver
# to all touchpads. See xorg.conf.d(5) for more information on
# InputClass.
# DO NOT EDIT THIS FILE, your distribution will likely overwrite
# it when updating. Copy (and rename) this file into
# /etc/X11/xorg.conf.d first.
# Additional options may be added in the form of
# Option "OptionName" "value"
#
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*"
EndSection
Section "InputClass"
Identifier "touchpad ignore duplicates"
MatchIsTouchpad "on"
MatchOS "Linux"
MatchDevicePath "/dev/input/mouse*"
Option "LTCornerButton" "0"
Option "LBCornerButton" "0"
Option "Ignore" "on"
EndSection
# This option enables the bottom right corner to be a right button on
# non-synaptics clickpads.
# This option is only interpreted by clickpads.
Section "InputClass"
Identifier "Default clickpad buttons"
In my /usr/share/X11/xorg.conf.d/50-synaptics.conf
file. And it should work as setting those options with synclient but ubuntu decides for some reason that I knows better and I can't override the setting.
Why? and, most importantly, how can I fix this?
Also: this question is a possible duplicate of X11 ignoring options in configuration for input device but that solution is ugly. I won't do that, but should I post this as a comment?
*: They will be triggered at the worst time, like, ALL THE TIME. Enough to drive me mad...
**: Where is the X.org config file? How do I configure X there?
