XPS 13 (2015 Dev Ed) glitchy trackpad issue

Just received the new XPS 13 Dev Ed today. The trackpad is very glitchy and I'm getting a lot of this kind of thing in /var/log/syslog. What gives? Any known solution?

Can you contact ProSupport? We need to be able to check when exactly yours was built.

Status was In Production until Monday... 

Is Pro Support something different than regular support?

ProSupport is our business class support.

We would need ProSupport to get your service tag so we can look into why you're having this issue. All 2015 XPS 13 DE's should be free of this issue.

That is, if you ordered the DE, ProSupport is what should be bundled with your system.

RE: XPS 13 (2015 Dev Ed) glitchy trackpad issue

Ok, that sounds good. I definitely ordered the 2015 DE but see no trace of Pro Support contact information in email or print. Should I be calling 1-800-456-3355?

Scratch that - after adding the product to my Dell account it does show up as ProSupoprt. I'll go through that channel. Thanks!

Hopefully they can make sense of the issue.  In the interim, you can add "psmouse.resetafter=0" to your kernel command line and it will work around the issue.

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"

Ditto here. Received the Developer Edition today and same touchpad issues as described, as well as same sort of stuff in /var/log/syslog. Every once in a while I'll also get the repeated key issue happening.

I'll reach out to ProSupport early next week.

FYI: Bios version is A03 and the wifi chipset is Broadcom BCM4352. I thought the developer edition is supposed to come with an Intel WiFi card.
