Touchscreen/Touchpad issues on Ubuntu 14.04 and Dell XPS 13

[maka]

Hi all, I recently installed ubuntu 14.04 on my Dell XPS 13 and most things are working well after a kernel 4.4.3 install and some other fixes for wifi, bluetooth that didn't work out of the box

Now, I am seeing that the the touchscreen does not seem to be working after a suspend. I also noticed that syndaemon (which I use to disable the touchpad while typing via syndaemon -i 1 -KRd -t) works better after the suspend/resume vs cold boot

One thing I have been able to see a difference so far is that after a cold boot, I have two Touchpad input devices for some reason..

Just cold booted:

Should I have 2 Touchpad input devices in the first place? Tailing the mouse handler in /dev/input (mouse0,mouse1,mouse2) the Synaptics mouse handler does not capture any events even when the touchpad is working. So I assume that means that one is extraneous and the other one is the actual one used by kernel/OS. My question is if it is not needed, how do I get rid of it since it may also be what is causing my conflicts with syndaemon not working? Can this be related to why my touchscreen is also not working after resume from suspend...

Thanks!!

Bump.. Anyone?

Hi maka,

I picked up a Dell XPS 13 (9350) last week, and I've been having the same problem with syndaemon. It can make for a miserable experience if you can't get "disable touchpad while typing" to work.

To get things working properly, I needed to disable the second touchpad device "SynPS/2 Synaptics TouchPad". I think it was mostly being ignored, and syndaemon was attaching to it instead of "DLL0704:01 06CB:76AE Touchpad", which was actually managing the touchpad.

I disabled it in the Xorg config file. I opened:

/usr/share/X11/xorg.conf.d/51-synaptics-quirks.conf

and added this entry:

# Disable generic Synaptics device, as we're using
# "DLL0704:01 06CB:76AE Touchpad"
# Having multiple touchpad devices running confuses syndaemon
Section "InputClass"
        Identifier "SynPS/2 Synaptics TouchPad"
        MatchProduct "SynPS/2 Synaptics TouchPad"
        MatchIsTouchpad "on"
        MatchOS "Linux"
        MatchDevicePath "/dev/input/event*"
        Option "Ignore" "on"
EndSection

Then I restarted Xorg by typing:

# sudo systemctl restart lightdm

And all was well. I'm not an Xorg config guru, so there might be a more precise way to do this, but it got the job done.

The file location and restarting Xorg might be slightly different on 14.04 -- I'm on 16.04 Beta 2 since it has the 4.4 kernel which is needed for Wifi to work.

I hope this helps you keep typing in the window you intended! FWIW, your hint at looking at "xinput list" is what got me going in the right direction for the fix, so thanks!

@ddarling. I bumped into your answer, and this is it! I thank you very much! Indeed, disabling the Synaptics driver causes syndaemon to interact with the driver that is actually used, and finally disable touchpad while typing is working. I am also on a fresh install of Ubuntu 16.04 on the Dell XPS 13 9350, so I could adopt your instructions without any modication.

And all was well. I'm not an Xorg config guru, so there might be a more precise way to do this, but it got the job done.

Looks like a very elegant solution to me, but then, I am even much less an Xorg config guru

I'm only seeing one touchpad on my Thinkpad and I'm having the issue of the touchpad not disabling so that i don't have to worry about accidentally bumping it. Any helps would be great. I figured asking here would be better then starting a new thread

Fantastic! This had been driving me crazy. Thank you!!

Thank you! This worked for me as well on a dell xps 15 9550 running Ubuntu gnome 16.04 with kernel 4.6

Thank you, thank you, thank you, thank you....

Thank you for writing this and thank you to Google for helping me find this while I still have some hair in my head. This time last week I had a mane to be proud of...
