I’ve got this XPS15 9560 laptop whose touchpad is not working as it is not responding to any input.
So far, at least I realize that the laptop says it always detects a plugged in mouse even when nothing is plugged in except the power cable. At reboot, a notification would say “touchpad is disabled because a mouse is plugged in” at reboot with or without a mouse connected.
The following is the screenshot of the touchpad setting page:
cat /proc/bus/input/devices I: Bus=0018 Vendor=06cb Product=7a13 Version=0100 N: Name="DLL07BE:01 06CB:7A13 Touchpad" P: Phys=i2c-DLL07BE:01 S: Sysfs=/devices/pci0000:00/0000:00:15.1/i2c_designware.1/i2c-8/i2c-DLL07BE:01/0018:06CB:7A13.0004/input/input33 U: Uniq= H: Handlers=mouse3 event20 B: PROP=5 B: EV=1b B: KEY=e520 10000 0 0 0 0 B: ABS=2e0800000000003 B: MSC=20
There’s a dmesg that says
[1.816739] psmouse serio1: synaptics: Your touchpad (PNP: DLL07be 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 firstname.lastname@example.org.
I tried adding psmouse.synaptics_intertouch=1 at kernel option using the yast2-boot loader but still no go.
