Hi everyone!
I’m opening a thread to report an irritating issue I’ve been facing since yesterday. I believe this behaviour appeared after I ran a dist-upgrade yesterday in the afternoon, during which lots of packages were updated (Gnome 3.28, Linux 4.15.8-1 etc.). The problem is quite simple: my laptop’s trackpad’s right and middle buttons now behave like the left one, making it almost impossible to fully use my laptop without the help of an external mouse. The laptop is an Asus X556UV, the system is openSUSE Tumbleweed with Gnome; the problem occurs both when using Wayland and Xorg, and both when using Linux 4.15.8 and 4.15.7.
Has anyone got any advice?
Let me know if you need me to provide more details about the issue.
Thank you in advance for your attention!
And nothing you can change about this in gnome-settings ?

Nope. In Gnome’s Control Center, in the Mouse & Trackpad section, the utility that lets me test the trackpad’s/mouse’s settings shows that the left, middle and right clicks are all detected as “primary buttons” when I press them.
A bug report is probably required, but first you could demonstrate the issue by capturing the button events generated with…
sudo libinput-debug-events
Also what does the following command report about your trackpad device?
libinput-list-devices
(ignore the other device output blocks)

Ok, that checks out as expected. It must be a Gnome-specific issue then.
Try creating a new user, and login to that account. Any difference with the button behaviour?
Also, what is reported by the following?
gsettings list-recursively org.gnome.desktop.peripherals.touchpad
gsettings list-recursively org.gnome.desktop.peripherals.mouse

When using the newly-created user, the problem persists. However, you are right: it must be a Gnome-specific issue, because I logged into an IceWM session (with my usual, “old” user account) and the touchpad buttons worked as expected.

Time to report as a bug IMHO.
Hi,
You can fix this in gnome tweaks under “Keyboard & Mouse” -> “Mouse Click Emulation” and set it to “Area”. For some reason “Fingers” is the new default even though no one uses this method.
This precisely resolved the issue I was having. Chalk up another one for confusion found between “Settings” and “Tweaks”… ::\
