If the one on the PC case got stuck, I would expect the machine to power down. So look for a key on the keyboard.

Swapping keyboards may be helpful in diagnosing the cause. It might be the only solution too. Otherwise, I can only reiterate my suggestions for masking the symptoms. > tail -100 /mnt/dos/home/zhou/.local/share/xorg/Xorg.0.log.old > [ 726.014] (EE) libinput bug: Key count for KEY_POWER reached abnormal values […] > [ 726.020] (EE) libinput bug: Key count for KEY_POWER reached abnormal values > [ 726.020] (**) Option "fd" "31" > [ 726.021] (EE) libinput bug: Key 116 is down 75 times. > [ 726.021] (EE) libinput bug: Key count for KEY_POWER reached abnormal values > [ 726.021] (EE) libinput bug: Releasing key 116 failed. 116 agrees with KEY_POWER in the source file.
