Bug ID: 104215
Summary: Middle-mouse panning does not work in some
applications on ThinkPad touchpad
Product: Wayland
Version: unspecified
Hardware: x86-64 (AMD64)
OS: Linux (All)
Status: NEW
Severity: normal
Priority: medium
Component: libinput
Assignee: wayland-bugs at lists.freedesktop.org
Reporter: montonen.niko at gmail.com
Hardware: ThinkPad X220
Software: Arch Linux, i3wm under X.Org, libinput 1.9.3
The default configuration for the device "TPPS/2 IBM TrackPoint" sets the
property "libinput Button Scrolling Button" to 2.
This configuration causes the "hold mouse3 to pan" functionality to break in
certain applications, such as KiCad and FreeCAD.
When the property is set to 3, panning works in KiCad and FreeCAD.
However, in KiCad this then causes the right-click to no longer open the
context menu. FreeCAD seems to be unaffected, but I've only spent a few seconds
with it (to confirm it was affected in a similar way).
On the other hand, KiCad manages to spawn a context menu with the right-click
when using their legacy codepath, that uses software rendering. The context
menu is broken in their new OpenGL codepath. I believe I will also have to open
a bug report with that project.
You however understand my trouble - behavior is extremely unpredictable.
When a regular USB Plug and Play mouse is connected to laptop, both panning
with mouse3 depressed and the right-click context menu work as expected without
problems in all use cases.
I've been smashing my head against the walls trying to play with different
property values, trying to find a configuration that works, but without
success. As such, I have included below anything I could consider relevant.
/etc/X11/xorg.conf.d/30-touchpad.conf:
Section "InputClass"
Identifier "libinput touchpad catchall"
MatchIsTouchpad "on"
MatchDevicePath "/dev/input/event*"
Driver "libinput"
Option "Tapping" "true"
Option "TappingDrag" "true"
Option "HorizontalScrolling" "false"
