Issue: 

User is unable to control device screen through mouse clicks.


Solution:

This issue is observed when the platform is opened using Chrome/Firefox on Touch-screen laptops. Disabling the touch on the browser will solve this problem.

The issue is not observed with other browsers.


Here's some detailed information - 

The problem could be with Touch-screen laptops + Chrome/Firefox. The VNC Client that we are using, doesn't support the Touch Screen devices very well. See here.

It is possible that a faulty device driver tells the Chrome/Firefox browser that a touchscreen device is available, but Chrome/Firefox decides not to sent the MouseEvents to the VNC.

If your Laptop doesn't support the TouchScreen functionality, or the device drivers are improper, then you can direct Chrome/Firefox to not use the touchscreen capability.


Here are the steps for Chrome :-

  • Open Google Chrome
  • Type chrome://flags/ in the address bar and press Enter.
  • Click on Enable touch events > Disabled.

  • Click on Relaunch Now.


This will disable the touch events on Chrome allowing mouse clicks to act on the device.


Here are the steps for Firefox :-


  • Type about:config in the address bar and press Enter.
  • search for dom.w3c_touch_events.enabled flag
  • change the value to 0 from 2



This will disable the touch events on Firefox allowing mouse clicks to act on the device.
