Hi I've upgraded my two laptops and all touchpads stop to work (tracking works , only tapping doesn't work anymore).
I think it depends on disabled "touchpad" useflag on kde-plasma/plasma-desktop package Description: KDE Plasma desktop ╠ USE flag: -appstream -debug -gtk2 -gtk3 ╠ -ibus -scim -test -touchpad abi_x86_64 ╠ amd64 big-endian elibc_glibc ╠ fontconfig handbook kernel_linux ╠ legacy-systray mouse pulseaudio ╠ qt4 semantic-desktop userland_GNU there is this old bug about this : https://bugs.sabayon.org/show_bug.cgi?id=5241 I think the problem is builtin module in kde-desktop to manage touchpad tap not about touchpad recognition USE="touchpad" emerge plasma-desktop fix the problem Consider to enable "touchpad" useflag globally or per package :) Cheers
