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.

I tried the latest Fedora Rawhide and still had this issue.

[Desktop-packages] [Bug 1694225] Re: [Thinkpad T450s] Click lock effect on trackpoint left button when touchpad is disabled
I have the same problem on a ThinkPad Yoga 14 20FY. I can reproduce it with the touchpad disabled as described in this report. However, I find it much easier to reproduce (nearly 100% of the time) with the touchpad enabled, as follows: 1. With my left finger, hold down the trackpoint’s left button. 2. With my right finger, move the pointer with the trackpad. 3. Release my right finger from the trackpad. 4. Release my left finger from the button. The button has become “stuck” down! 5. Put a finger back on the trackpad. Now the earlier button release gets recognized. evtest on the trackpoint (ETPS/2 Elantech TrackPoint) shows that the trackpoint knows the button is pressed at step 1 and released at step 4, but evtest on the touchpad (ETPS/2 Elantech Touchpad) shows that the touchpad thinks another copy of the button has been pressed at step 1 and not released until step 5. The problem is still present in kernel 4.12-rc6 from the mainline archive. (I haven’t been able to figure out if enabling the new drivers in 4.12 is supposed to require manual configuration, but simply booting into the new kernel didn’t fix it.) -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to xserver-xorg-input-synaptics in Ubuntu. https://bugs.launchpad.net/bugs/1694225 Title: [Thinkpad T450s] Click lock effect on trackpoint left button when touchpad is disabled Status in xserver-xorg-input-synaptics package in Ubuntu: Confirmed Bug description: Click lock is a behavior where you do a button click once, the system will register the click as "holding the button".

More Informations: This issue doesn't happen on other OS like Windows, but I can confirm it happens on most modern linux distro and DE I've tried (e.g. ubuntu v17/v16, kubuntu, ubuntu mate, xubuntu, lubuntu, linux mint, fedora, open suse, etc). So this issue must be coming from the synaptic touchpad driver, or maybe from the kernel (?) Also, the issue doesn't occur on older thinkpad models which doesn't use same clickpad type touchpad, e.g. T430 or X230. For newer thinkpad models (e.g. T460, X260, etc) which uses same clickpad design, same issue might exists too (need confirmation though).
