Version: (using KDE 4.2.0) OS: Linux Installed from: Slackware Packages When setting the mouse button order to left hand, it should only change the usb or ps2 mouse, but with a laptop it also change the button order for the touchpad, so it become unusable, when you do a simple touch it should produce a 1st button but produce e 3rd button. Its a big problem with macbook that has only one button.
I can confirm that configuring a left-handed mouse makes clicking on the touchpad produce a secondary mouse button click. This should be corrected. Furthermore, when scrolling is configured for the touchpad edges, it is disabled when the mouse is configured for left-hand usage.
One of many annoyances for me when moving from KDE 3.x to KDE 4.2 (Ubuntu 7.10 -> 9.04)
This is still an issue with KDE 5.12. Also see bug #220481 which is the same issue - one should be set as a dup of the other.

Workaround for now: 1. After setting your mouse to be left handed, run `xinput list` and note the `id` of the touchpad device. 2. Run `xinput get-button-map <id>`, where "<id>" is the touchpad device id from step 1. For example: `xinput get-button-map 13`. it should show "1 2 3 4 5 6 7". 3. Set a button map that reverses the actions of the primary and secondary "taps", by running: `xinput set-button-map 13 3 2 1 4 5 6 7". After setting up the reverse map, and left-handed mouse in the mouse KCM, primary tap should function as a primary mouse button while a secondary tap (a two finger tap on my system) should function as a secondary mouse button (the left button for a left-handed mouse).

These settings are now configurable independently for nice and touchpads when using the Libinput driver.
