Trackpad issue

Yep -- same is happening here. Look in /var/log/syslog and you'll see messages like "psmouse serio1: TouchPad at isa0060/serio1/input0 lost sync at byte 1"

I'm pretty surprised that it arrived behaving like this. It's certainly a known issue. 

I just upgraded to kernel 3.19.5 and the trackpad issue went away! So there is hope.

Unfortunately my wireless adapter stopped working. In any case, the fix for this is probably going to involved a kernel upgrade.

There shouldn't be trackpad issues like you describe on 14.04 specifically with the developer edition, but if you are having issues maybe there is a factory problem still.  A few tips:

1) Contact prosupport, let them know and they can dig into what's going on.

2) You can add the kernel command line option psmouse.resetafter=0.

3) Upgrade to the 3.19 kernel as mentioned above from 15.04.  The Broadcom wireless package in 15.04 does work as well.  

4) Jump to 15.04.  Broadcom wireless is not installed on the live image, but I believe gets installed for you if it's detected it's needed.

Thanks for the info, pinmode. I would attempt the kernel upgrade but I don't know what's worse, an inconsistent cursor or no wireless adapter.

Just a FYI, I tried 15.04 (Live) which seemed to resolve the trackpad issues (didn't notice any random cursor jumps to the corners) but there was no sound as well as no wireless adapter.

At this point, I'm sort of at a loss for what to do.

Yeah, this is lame. 

I've been directed to contact ProSupport on the other related thread that I started about this. Clearly the machines weren't tested before shipping. 

Mario,

Thanks for the quick response and suggestions. I'll give them a shot and report back.

So I just upgraded the kernel and that seems to have resolved the trackpad issues. The only nagging issue is that even with the "Disable While Typing" enabled I'm still getting a bunch of random mouse clicks while typing because it's recognizing the heel of my palm as a finger.. Any suggestions other than playing around with the Synaptics touchpad settings?

How exactly did you upgrade the kernel? Were you able to do that seamlessly without having to rely on ethernet while the wireless driver was updated?

Resolution: added psmouse.resetafter=0 boot option.

Also separately, the default touchpad tap response time is pretty slugglish and can be changed to be more responsive with "synclient SingleTapTimeout=1"

And your wireless adapter continued working?

For the kernel upgrade I just consulted with this.

http://ubuntuhandbook.org/index.php/2015/03/upgrade-kernel-3-19-3-ubuntulinux-mint/

It was very straight forward and painless.

Yes it's working just fine.

Though an additional new feature popped up :) I currently can't right (secondary) click with anything other than a mouse. I've tried both tapping, clicking, AND holding the right control button (which has a contextual menu icon on it) and doing a primary click. None seem to be working. When I go to the Mouse & Touchpad System Settings and go into Test Your Settings none of the above mentioned trackpad attempts registers a click of the Secondary Button, only right clicking the USB mouse does.

EDIT: A two finger click or tap on the trackpad seems to register as a secondary click.

I'll give this a shot tomorrow:

But any other suggestions for this or the annoying trackpad movement while typing would be greatly appreciated!

UPDATE: Total newb, I need to play around with the synclient settings.

Came across this today to get the wireless adapter working in 15.04 if you still need help...

What settings did you end up with for synclient? I currently can't click and drag a window after performing the kernel update, among other oddness.

I'm currently doing that via a double-tap and drag. Does anyone know if this trackpad would support a click and drag?
