We just bought two laptops and both experience the same issue. While using the touchpad, suddenly, they start generating false clicks and that messes around with anything you do using touchpad. My colleague is a windows user while I am an Ubuntu user. While in Windows it seems to appear less often, in Ubuntu is like a click fest. The biggest issue is that after this anomaly starts the clicks are generated even if you don't use the touchpad. Try to watch an youtube while this is happening ....
As I cant seem to get in direct contact with Dell Support I hope for a response here.
My question is: Should we wait for a BIOS update in the next couple of days or should we return the units back for replacements?
Out configuration is:
XPS 13 9360, I7, 16GB RAM, 1T SSD, QHD+
You can go into the touchpad settings in Windows to adjust the sensitivity settings as well as in Ubuntu. In Ubuntu and in Windows 10 you can click the links below to adjust the settings.
Indeed it is detected twice. I will remove the psmouse for further testing however I also own an XPS12 (2013) and there it is also detected twice but I don't experience the same behavior. I will provide further feedback after I test this. Thank you!
After a few hours of usage, with psmouse driver unloaded, I can't say it is fixed or that there is big improvement. The thing is, this behavior does not occur any time and I cant seem to find what it is triggering it. I will try Jesse's suggestion now.
I'm sorry my suggestion didn't help!
Post your current touchpad settings (using synclient) and I'll set mine up the same way to try to help.
Have you changed any touchpad settings or window focus settings in settings or in gnome-tweak-tool?
My touchpad didn't work at all, the same fox XPS 13 9360.
Service man came to me and he replaced touchpad with new one but it didn't help. Than he reset BIOS (new one 1.0.7) into manufacturer settings and it helped, touchpad started to work in BIOS.
In Windows touchpad still didn't work. So than he removed "I2C HID Device". Than he click to scan for new hardware and touchpad has been istalled back and is working fine.
Maybe reseting BIOS will help you too.
First of all, this is for LINUX users.
It seems that working with the touchpad sensitivity did it for me. I think this is very specific to each device (its physical construction) so I don't know if my settings will work for others.
After testing a few values I ended up wtih these settings: Synaptics Finger (298): 35, 40, 100. My original settings were 25 30 0
To set the new parameters use this command:
xinput --set-prop 12 "Synaptics Finger" 35 40 100
And a bit of help about what each number means:
1. Option "FingerLow" "integer"
When finger pressure drops below this value, the driver counts it as a release. Property: "Synaptics Finger"
2. Option "FingerHigh" "integer"
When finger pressure goes above this value, the driver counts it as a touch. Property: "Synaptics Finger"
3. Option "FingerPress" "integer"
When finger pressure goes above this value, the driver counts it as a press. Currently a press is equivalent to putting the touchpad in trackstick emulation mode. Property: "Synaptics Finger"
UPDATE: I was wrong. It appears this did not fix my issue 100%. It is less often but it still occurs from time to time and, I think I know now how to reproduce it. Basically the touchpad goes nuts when you combine taps/drags with hard clicks. For example when you try to resize a window by first hard clicking and hold the border then drag. And I have tested this both on Windows and on Linux.
Dell support pls let me have your opinion on this.
