Hi, On the XPS 13 9360 and 9370 xinput sees two touchpads instead of one: ⎡ Virtual core pointer id=2 [master pointer (3)] ⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)] ⎜ ↳ DELL07E6:00 06CB:76AF Touchpad id=12 [slave pointer (2)] ⎜ ↳ SynPS/2 Synaptics TouchPad id=17 [slave pointer (2)] dmesg also gives me the following: [ 1.429811] psmouse serio1: synaptics: Your touchpad (PNP: DLL07e6 PNP0f13) says it can support a different bus. If i2c-hid and hid-rmi are not used, you might want to try setting psmouse.synaptics_intertouch to 1 and report this to linux-input@xxxxxxxxxxxxxxx. The Dell one is the real touchpad, the other one is an artifact of the psmouse driver. Weird touchpad freezes and jittering issues can be observed when both of these devices are there. The general advice on the web is to blacklist the psmouse driver. (This is also published by Dell as a .deb package which contains a config file doing just this.) However, on Fedora I cannot blacklist the psmouse driver because it is compiled built-in instead of as a module. Could you guys change the Fedora kernel config to compile it as a module instead? Thanks & best regards, Timur
So assuming nobody else has objections, I think it's okay to at least try this on rawhide and see if it uncovers any other problems.
