Left-hand Mouse Setting

English Hardware
1

My SSD drive died exactly the day the Leap 15 was release. (What are the odds?) So, I installed a new SSD and downloaded and installed the ISO for Leap 15. No problems at all until I used Leap 15 to swap my mouse buttons to Left-Handed. It swapped about half of the buttons/action to left-handed, but left the other half right handed. So, I’m never sure what button to push for any action. (No, I have mapped it yet.) It’s too frustrating to use. I never know what button to push. I don’t see any forum messages that anyone else is having the same problem, so I’m not sure anyone will be looking into it. That pretty much leaves me with finding a real left-handed mouse - which isn’t easy.

Anyone else having this problem? Any idea of a temporary or long-term fix for it?

Thanks,
Clyde

Which desktop environment? I’ve only ever owned basic mice and although I’m left-handed I only use them right-handed, but I’ve never had a problem with the KDE utility for switching (testing purposes only). If you have an ‘exotic’ mouse, probably only button mapping is going to help here.

My left-handed mouse worked fine until Leap 15. I have a right-handed mouse for my wife’s login and a left-handed mouse configuration for my login. No problems until Leap 15. Absolutely nothing “exotic” about our ROCCAT Kova (setup as left-handed) or the Logitech (setup as right-handed). I have no idea what changed moving up to 15, but it’s broken.

Again, which desktop?

The ROCCAT Kova is the one I’m trying to switch the keys to make left handed. It worked before on previous versions of Leap.

Thanks,

Try setting the mouse to left-handed operation with xinput like this…

xinput set-prop "ROCCAT ROCCAT Kova" "libinput Left Handed Enabled" 1

Does that do the trick?

…and please as already requested tell us which desktop environment you are using!

Leap 15 KDE Plasma (Wayland)

Result:

unable to find device ROCCAT ROCCAT Kova

The use of Wayland is probably the cause of the issue here. Wayland is still work in progress, and you may need to switch back to Xorg ( perhaps.

Wayland experience installed by default. It will just be a matter of selecting “Plasma (Wayland)” in the session list of the display manager before logging in.

It can also be changed using ‘update-alternatives’ as explained in the release notes

Thanks!

That seems odd that openSUSE would default to a buggy system, when Leap is designed to be the rock solid version.

Being flexible,

I made a clean install of Tumbleweed in an attempt to solve a similar problem - KDE not using Wayland.

First the most recent Tumbleweed update “lost” the left-handed setting"

On restoring the left handed settings the menu functions of KDE became unavailable and the mouse unresponsive (IceWM although resolutely right handed seemed fine)

The new install worked fine until setting left-handedness then the unresponsiveness returned and KDE becomes unuseable

I don’t know if it is a Tumbleweed or KDE problem

Perhaps this is relevant…
