I revisted this bug report from another PC to make some amendments/clarifications. Thereby I realized that I had uploaded a very old diagnostic and replaced it now with the current one.

dont’t think this is necessary

Is this the same problem as reported by @sofo_sreseli with the important difference that my touchpad used to work the last three years?

Update: the touchpad is still not working. I connected yet another (wireless) USB mouse, which worked ok and was able to (re-)connect the Bluetooth mouse.

I grepped for touchpad in an eos-diagnostic output from the time where the touchpad was working and from today, but I cannot see any difference between both:

older diagnostic (touchpad working):

Finally I was able to solve it myself: there is a special function key to disable the keypad, which I had not yet realized that it exists. The setting survives a reboot. I must have hit this key without intention.

where is the setting you are telling about please tell

F7 together with the blue function key labeled FN toggles the touchpad on off.
