I just bought a dell xps 13′‘ 9360 using the latest by today 1.07 BIOS version and it’s hard to write a paragraph of text without having the cursor jumping to somewhere else. So the only way to get proper text using the computer is by hitting ctrl+z every single minute of writing.
I remember my previous experience with dell xps 13′‘ 9343 where the same thing happened but much worser and was a known issue, fixed (if I'm not wrong) with a BIOS update later.
Is this something that is a known issue for dell? is there already a fix out or a fix coming?.
Thanks in advance.
I had the same issue. I traced it back to the touchpad being detected twice, once by the psmouse driver and once by the newer i2c interface. You can run xinput in a terminal from unity. KDE actually gave me a popup message saying that two touchpads was an unsupported configuration.
The fix, for me, was to create /etc/modprobe.d/xps13-9360.conf as root with the following line in it:
Then, run "update-initramfs -u" and reboot. After that, palm rejection and other things start to behave.
I'm pretty sure my 9333 had the same issue when it was new, and it was fixed upstream at some point.
Go to "Settings" > "Devices" > "Mouse & Touchpad". Under the "Touchpad" section does it say that "Your PC has a precision touchpad"?
Thank you for writing to us!
On both these system that you have mention there are no issue with the cursor jumping or any erratic cursor issue. We would suggest you to update the touchpad drivers and also update the BIOS on both the system which should ideally fix the issue and also ensure the setting are correct .
Kindly private message the service tag and email address.

It does not mention a precision touchpad.
I'm already using the latest BIOS, regarding the touchpad drivers I just have Ubuntu updated to the latest possible all updates applied. I'm using the kernel 4.4.0-45.
The rest is all default factory settings, so I guess that should just work.
mine does the same thing.
During testing, I briefly ran ubuntu 16.10 with GNOME and found it was behaving as though I had both drivers loaded again even when psmouse was blacklisted. I found out that GNOME 3.20 no longer supports the synaptics input driver. Installing xf86-input-libinput made the touchpad behave better again (although the touchpad behaved slightly better under synaptics).
Found an earlier report that came to the same conclusion I did.
So, run 'xinput'... if you see both "SynPS/2 ... Touchpad" AND "DLL... Touchpad", then one needs to be disabled. My approach just avoids loading the driver for the first. The approach taken in the other link configures Xorg to ignore the first.
This fixes the issue. Would be great to have this fixed upstream.
Updating drivers does nothing. I've bought the 9360 early on and updated it with all the new drivers as they are released. Still the worst and least predictable trackpad I've ever used.
