Hi, Nikolaus, If you have a time, please try below debug method. Download below file, copy it to your system and unpack. https://www.filesanywhere.com/fs/v.aspx?v=8b716a8e5b6773baa799 Procedure ex: #cd Desktop/LinuxModDebug #sudo chmod 755 linux_kr_rebuild_tool_hid.sh #sudo ./linux_kr_rebuild_tool_hid.sh /init linux-4.10.tar.gz #sudo ./linux_kr_rebuild_tool_hid.sh /build DebugSrc After that Touchpad all features should work. If Touchpad does not work, something error appears on dmesg.

No matter if there's a dmesg entry or not, at the moment this patch will make life much worse for at least some EliteBook owners. Is there anything I can do to help you debug this?
