Oddly, this issue has appeared suddenly in a few occasions but now has been worsening over the last month:

Every time my Lenovo Thinkpad T14 wakes up from suspend, my left mouse click is unresponsive- both the trackpad/touchpad and the physical mouse button. The only thing that works is to force via terminal into reboot.

The right click seems to still work normally. To me, it seems like an incompatibility of the Trackpad Driver-Ubuntu version or Kernel release. Any suggestions on what's worth upgrading?

**UPDATE: I just found out that when I run the following commands (suggested in this post Is there a way to "restart" the touchpad driver?)

sudo  modprobe -r psmouse

and then

sudo  modprobe psmouse

it creates the exact SAME FAULTY BEHAVIOR of my left mouse click, as the one I experience after re-suspend. It can then be fixed only with xinput disable 11 and xinput enable 11 (11=Touchpad id from xinput list)

Any clues?

Out of experience: most probably this is a hardware issue - either your mouse button is about to die or the touchpad is giving up.

I had exactly the same behavior on older Thinkpad HW. modprobe psmouse command helped intially, sometimes only reboot fixed it up until my touchpad gave up totally. Replacing the palmrest fixed everything.
