I've read way too many pages on the issue over the past two or so years but nothing seems to work for me up to now.
Is it possible to disable doubleclick altogether instead of changing doubleclick speed as here https://help.ubuntu.com/stable/ubuntu-help/mouse-doubleclick.html.en ?
My mouse multiple clicks when I single click about 80% of the time, which makes it really difficult to use. I've tried various mice and they all do the same. So the assertions here (https://help.ubuntu.com/community/MouseCustomizations) and here (https://help.ubuntu.com/stable/ubuntu-help/mouse-doubleclick.html.en) that the mouse must be faulty do not seem to apply in my case. Both mice listed below in the "xinput --list" output present the same problem.
I've already lost some documents as a result of extra clicks causing documents to be overwritten due to incorrect options being accepted by extra unwanted clicks.
What I would like now is to disable doubleclick for the left mouse button altogether and enable it on another button instead, e.g. to doubleclick when I press down the middle button. Could someone guide me on how to achieve this? Many thanks.
ps. I've already tried options such as this mouse sometimes doubleclicks when i click once and https://ubuntuforums.org/showthread.php?t=316441
