[Bug 1694225] Re: [Thinkpad T450s] Click lock effect on trackpoint left button when touchpad is disabled
apport information ** Tags added: apport-collected artful ** Description changed: Click lock is a behavior where you do a button click once, the system will register the click as "holding the button". In laptop Thinkpad T450s I have an issue where the disabled touchpad sometimes could trigger the click lock when clicking the trackpoint (red pointing stick)'s left button. Basically it happens randomly when my palm is touching the touchpad while I'm clicking the trackpoint left button. But I found a way to make the bug occurs easily: 1. Disable the touchpad first. You can do this from ubuntu's "Mouse & Touchpad" setting. 2. Put your two fingers on the touchpad (whether your two fingers are tapping or pressing the clickpad, it doesn't matter). You could use your left hand's index and middle finger for this. 3. While your left hand's two fingers are on the touchpad, use your right hand to click the trackpoint's left button once (don't hold it) on the desktop area, then immediately move the cursor with the pointing stick. 4. If the click lock effect gets triggered, you would see you make a selection drag on the desktop area. If the click lock doesn't happen, repeat again the step 3.
