Re: XPS 15-9575 2-in-1, touchpad freezing

Jump to solution

So I finally have a workaround(not great though) on linux

Problem:  My touchpad randomly freezes while in use(wont click or move), then starts working about after a bit or when i open and close the laptop.

Solution:

On fedora if i go to mouse settings and disable tap to click.

Then in gnome tweak tool i go to the mouse settings and disable "disable while typing" 

 

When I do both of those things the issue is gone.  Takes a bit to get used to having to actually click the mouse button on my touchpad again but works.  I'm guessing there is a hardware or driver bug where enabling and disabling the touchpad over and over causes it to fail to enable  once and awhile.

I don't think that's the fix for everyone. My touch pad was freezing, and is now completely nonfunctional in windows, but in Ubuntu it works just fine. It also works, all be it in a crippled way (no 2 finger scroll) if I disable the "HID-compliant touch pad" in device manager under the "Human Interface Devices" tab. It's possible that this is still related to hardware failure, and I'll be trying your method as soon as I can.

Respect to HQ216493 from Dell forums here, he gave a solution and at least it's been couple of hours as it works, which is much longer than any other solution 🙂 Anyway, as he said, try disabling 3 and 4 fingers gesturs as well as pinch-to-zoom gesture in windows touchpad settings. Things should get better, that's for sure.

upd. damn, the next day it all started again 😫

To resolve the problem try downloading the newest driver from intel using their Intel-Driver-and-Support-Assistant get the installer from intels website. https://downloadcenter.intel.com/download/28425/Intel-Driver-Support-Assistant - you get a new Radeon RX Vega M Graphics version number 24.20.11001.8003. After you restart windows go to touchpad settings and change your touchpad sensitivty to HIGH and increase the cursor speed to 6. This will improve the touchpads use on a 4K screen. The intel driver support assisatant is excellent. The video driver from dell does not appear to support windows 1909 (im not sure if this is the problem because I let my Dell XPS update windows imediatlley out of the box)

interesting. few months back my intel support assistant offered me 25.20.15002.58 vega m drivers, which seem to be newer. still having freezing issues no matter what I do change in touchpad settings

Try setting the trackpad sensitivity to low, that seems to have sorted it for me

I'm on archlinux, this has been driving me insane. So many guesses and so many fixes that never worked! The bottom half of touchpad just decides to stop responding for a few seconds or a minute tops! And sometimes just lags and stutters it's unbearable!

For windows users, it seemed a solution that worked with many people was to remove "HID compliant device" from their pen device options in device manager. For other window users, removing all "HID compliant" devices from their device managers.

But what about linux users? First, I tried to search what drivers I had

xinput --list

I noticed some wacom pen and finger drivers. I then added a conf to prevent libinput from handling them... that didn't work. I wondered if just loading the drivers was the problem... The driver loaded was wacom, so I blacklisted wacom (create file /etc/modprobe.d/nowacom.conf), inside it, put the following

blacklist wacom

Save and reboot. Problem gone! And as a perk, it seems archlinux loaded other drivers so screen touch is still working and maybe pen might still be working. I never used screen touch or pen, so I can't tell what I might have lost by abandoning wacom drivers, but I can finally use my touchpad without going insane 🙂 I don't know about other distros, but I presume it's the same. Please report back if this worked for you.

Weird, but setting sensivity low seems to have the solved the issue, at least mostly! Thanks @mcastro123!
