The first time I purchased Dell's XPS 13 notebook was in 2015 and couldn't be more satisfied. Now I own Dell XPS 13 9380 with Ubuntu 18.04 pre-installed. After initial testing the hardware, I immediately installed a fresh 19.04 and everything was well supported.
However there is no proper was of enabling or disabling the Touchpad. In the Knowledge Base provided by Dell, there is no mention of Ubuntu even though the OS is officially supported. Dell had another link to the Linux issue which didn't look easy to follow. So I am sharing a more simpler fix.
Steps to Follow
Open the Terminal on type the command:
$ xinput list
You will get the output based on the devices attached to you system:
⎡ Virtual core pointer id=2 [master pointer (3)] ⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)] ⎜ ↳ ELAN2930:00 04F3:2930 id=10 [slave pointer (2)] ⎜ ↳ Logitech MX Anywhere 2S id=21 [slave pointer (2)] ⎜ ↳ DELL08AF:00 06CB:76AF Touchpad id=11 [slave pointer (2)] ⎣ Virtual core keyboard id=3 [master keyboard (2)] ↳ Virtual core XTEST keyboard id=5 [slave keyboard (3)] ↳ Video Bus id=6 [slave keyboard (3)] ↳ Power Button id=7 [slave keyboard (3)] ↳ Sleep Button id=8 [slave keyboard (3)] ↳ Integrated_Webcam_HD: Integrate id=9 [slave keyboard (3)] ↳ Intel HID events id=12 [slave keyboard (3)] ↳ Intel HID 5 button array id=13 [slave keyboard (3)] ↳ Dell WMI hotkeys id=14 [slave keyboard (3)] ↳ AT Translated Set 2 keyboard id=15 [slave keyboard (3)] ↳ Logitech MX Anywhere 2S id=22 [slave keyboard (3)]
For my case
DELL08AF:00 06CB:76AF Touchpad id=11 [slave pointer (2)] is line of which is telling me that the Touchpad is using the ID
Now all I have to do is to disable this device using the command:
$ xinput --disable 11
Try using the Touchpad and it will not respond. To enable it again:
$ xinput --enable 11
And its done! Just in case you want to get the details of this device, run the command:
$ xinput list-props 11
What if it didn't work?
In that case look for the Knowledge Base I have shared in the start and following those instructions.
