I've got a Dell 14R with touchscreen with Ubuntu 14.04. When I start Google Chrome by clicking the launcher with the TouchPad or with the Super+ combination, touch support in Chrome doesn't work. When I touch some element, it only gets focus, but doesn't activate the element (button, field, etc). And touch gestures don't work. In the other hand, if I start Chrome by touching the launcher button, touch scroll works in Chrome, even flicking to left does back to the previous page, etc. It doesn't makes sense to me, but is always like this, even across reboots. Anyone can confirm this? Any idea on how to fix?

I believe the repo version of Chromium has some support for touch screens. Try that instead.– saiarcot895May 24, 2014 at 14:24

Chrome has too, but in my case, only works if I start it by touching the unity launcher...– Luis Fernando P. GonzalezMay 25, 2014 at 13:50

Ah, my bad. I misunderstood the question.– saiarcot895May 25, 2014 at 13:54

That problem could be solved for me with Chrome's --touch-devices
command line parameter.
Determine X's input device id in a console by
xinput list
leading to
google-chrome --touch-devices=10
on my system.
To make Chrome always use this CLI flag, see: How to set CLI flags for Google Chrome?

1Alex, would you mind explaining your solution a little more thoroughly. I'd like to try it but am a bit lost as to what you mean. How do I engage chrome's command line?– user298727Jun 28, 2014 at 20:44

3@user298727 Open a console and run
xinput list
first. The command's reply gives you the touch screen's device id. Start Google Chrome by enteringgoogle-chrome --touch-devices=10
in that same console. The console is just the command line environment from which you call Chrome. Follow that link on how to open the console. Please note, that you have to start "terminal" or "gnome-terminal" depending on your os.– alexJun 30, 2014 at 7:18 -

there is this, but it's not perm: askubuntu.com/questions/78638/… Nov 5, 2014 at 19:34
UPDATED Answer:
Edit
~/.profile
and add the following to the end of the file:export CHROMIUM_USER_FLAGS="--touch-devices=`echo $(xinput list | grep 'Virtual core pointer' | awk 'match(\$0, /id=/){print substr($0, RSTART+3, RLENGTH-1)}')` --touch-events=enabled --enable-pinch"
Log out and then log back in.
Start Google Chrome as normal
TIP: You may have to change "Virtual core pointer" string in the command above to the name of your "master pointer" touchscreen input device in the command above. Just use xinput
command to find the name of your device.
NOTE: I am on Ubuntu 15.04 using /usr/bin/google-chrome-stable
OLD Answer:
I have Ubuntu 14.14. This worked for me:
Make a shell script to start Google Chrome browser called
start-chrome.sh
.I put mine in:
/usr/local/bin/start-chrome.sh
Add the following to the file:
#!/bin/bash /usr/bin/google-chrome-stable --touch-devices=$(xinput list | grep Touchscreen | awk 'match(\$0, /id=/){print substr($0, RSTART+3, RLENGTH)}') --touch-events=enabled --enable-pinch
Basically, I am using the
xinput list
command and greping for "Touchscreen" and finding it's corresponding id. You may have to change "Touchscreen" to the name of your touchscreen input device in the command above.Edit
/usr/share/applications/google-chrome.desktop
. Find all occurrences ofExec=google-chrome-stable
and replace it withExec=start-chrome.sh
NOTE: I believe this solution will work until you update Google Chrome (via apt-get upgrade
) and the google-chrome.desktop
file is overwritten. You will need to follow step 2 above to fix it.

You solutions is smarter than the others. But on 16.04 with the newest chome 50 (chromium 49) it is not working on my side. Two finger scrolling works, with one finger I always select the text. Any ideas what else can go wrong or what I could test? Apr 30, 2016 at 9:27
You could try enabling touch events under Chrome flags:
- Navigate to
chrome://flags/#touch-events
and set it to enabled - Restart Chrome
