I have installed Lubuntu 20.04 on my RedmiBook 15 and I have checked single click to activate items, but it still doesn't work (can't tap to open item). I still need to use the touchpad's left click to open items though.

How do I fix this?

found the solution https://major.io/2021/07/18/tray-icons-in-i3/ , xinput then xinput list-props of touchpad name, and set the libinput Tapping Enabled (322) to 1

Run xinput to show the touchpad name. Then run xinput list-props "touchpad name" with the output touchpad name, and change the libinput Tapping Enabled (322) value from 0 to 1

Start with the xinput command to determine which devices are on your system. If xinput isn't installed run sudo apt install xinput to install it.

Example output of xinput:

➜ xinput
⎡ Virtual core pointer                      id=2    [master pointer  (3)]
⎜   ↳ Virtual core XTEST pointer                id=4    [slave  pointer  (2)]
⎜   ↳ SynPS/2 Synaptics TouchPad                id=12   [slave  pointer  (2)]
⎜   ↳ TPPS/2 Elan TrackPoint                    id=13   [slave  pointer  (2)]
⎣ Virtual core keyboard                     id=3    [master keyboard (2)]
    ↳ Virtual core XTEST keyboard               id=5    [slave  keyboard (3)]
    ↳ Power Button                              id=6    [slave  keyboard (3)]
    ↳ Video Bus                                 id=7    [slave  keyboard (3)]
    ↳ Sleep Button                              id=8    [slave  keyboard (3)]
    ↳ Integrated Camera: Integrated C           id=9    [slave  keyboard (3)]
    ↳ Integrated Camera: Integrated I           id=10   [slave  keyboard (3)]
    ↳ AT Translated Set 2 keyboard              id=11   [slave  keyboard (3)]
    ↳ ThinkPad Extra Buttons                    id=14   [slave  keyboard (3)]

The touchpad is the second entry in the first group: SynPS/2 Synaptics TouchPad. Now you can list all the properties of this device using the id number (12 in this case) or the full name:

➜ xinput list-props "SynPS/2 Synaptics TouchPad"

    Device Enabled (187):   1

    libinput Drag Lock Buttons (349):   <no items>
    libinput Horizontal Scroll Enabled (350):   1

The important line in the output is this one:

libinput Tapping Enabled (322): 0

Turn on tap-to-click for the touchpad:

xinput set-prop "SynPS/2 Synaptics TouchPad" "libinput Tapping Enabled" 1

Your tap-to-click should now work. If it doesn't, go back to the list of input devices and double check that there isn't another touchpad. Some laptops show multiple touchpads even though there's only one in the system. This is due to extra buttons being labeled as a touchpad on some laptops.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
