I ended up toggling some of the mouse options for scrolling and then it seemed to be fine. I didn't dive into any xorg configs or what not.  I ended up installing Arch on it and it worked fine without any tweaking.

my 9360 cursor jumps erratically.  driving me crazy.  I try to type without touching it and it still happens.  

hmm. did write a lengthy reply, but it got lost after captcha, maybe because I used three links? (before there were "this forum has been turned to moderated or similar" messages, but this time it just doesn't show up)

So short form: synaptics driver and configuring it as clickpad gave much better experience with the 9343 XPS 13, maybe it also helps for the other models. 

Touchpad freeze still occurs, but very seldom in regular use.

EDIT: Argh, it did show after all, so sorry for double-post..

at least with the 9343 XPS 13 the synaptics driver was much better experience than libinput for me. (with libinput scrolling was inaccurate/a pain, see http://en.community.dell.com/techcenter/os-applications/f/4613/p/19985678/20925652#20925652 

when using synaptics driver, make sure to configure it as clickpad, that sorted out all erratic cursor movement for me, see also the following post for a xorg config snippet (make sure to adjust the match rule if different hardware is used)http://en.community.dell.com/techcenter/os-applications/f/4613/p/19682746/20910510#20910510

The touchpad still freezes occasionally (very likely when when the cat steps on it, but only very seldom in regular use): http://en.community.dell.com/techcenter/os-applications/f/4613/p/19681145/20898266#20898266  

I received a Dell 9360 a few weeks ago - very excited to jump over the walled garden of Apple. I had the same problem with the trackpad and even more problems with the keyboard. I made sure I wasn't hitting the trackpad while typing -- cursor would go crazy and the wrong text was in the output. There was also a blemish on the keyboard (between the 3 and 4 key).

I lost 3 weeks of development over this "developer edition". I sent the machine back to Dell for a refund. I've lost all confidence in the brand -- this was the exact issue that send me to Apple in the first place. I have a new macbook pro now, but I'm not truly happy with this solution either. The Mac runs perfect -- but I want to run Linux and avoid Apple for ethical / philosophical reasons.

Looking into System76 now....

Good luck!

My first 24 hours with this laptop were spent angry because of the touchpad. I didn't experience the "stuck" behavior (that I can remember), but blacklisting psmouse addressed most of my gripes.

Still struggling with the trackpad on the XPS 13 9360. Nothing seems to solve the problem. The pointer jumps around by itself, clicks and closes applications, scrolling is erratic, the pointer disappears, etc.

I continue to update all new drivers, tweak the settings, and still it is a nightmare.

Definitely feel the reviews are biased, and XPS 13 with its terrible trackpad and keyboard is only gaining points in its *** appeal in the looks department.

I wish I got an X1 Carbon or an LG Gram instead. Terrible.

Also had a similar problem with the XPS 9550 touchpad in Ubuntu. Turns out the issue is that two touchpads are detected. I solved it by ignoring the PS/2 one

You can try putting the following in /etc/X11/xorg.conf.d/50-synaptics.conf

Section "InputClass"

  Identifier     "disable duplicate touchpad"

  MatchProduct   "SynPS/2 Synaptics TouchPad"

  Option         "Ignore" "on"

EndSection

@Malshafey,

Everything guys commented is not working out well for me.

I'm xps 13 developer edition(9360) user, Is there any solution to resolve trackpad issue?
