Disable touchpad upper left corner

in flag

On my Thinkpad L13 with Elantech Touchpad running Ubuntu 20.04 I want to disable upper left corner of touchpad to avoid double contact when I click or keep my finger on the left mouse button and at the same time move mouse pointer. The problem is if there is a contact in the corner I can't move pointer with another finger.

xinput output:

⎡ Virtual core pointer                      id=2    [master pointer  (3)]
⎜   ↳ Virtual core XTEST pointer                id=4    [slave  pointer  (2)]

I tried: synclient AreaTopEdge=1000 but this only disables the sensitivity in the upper area but still not allow to move mouse pointer with another finger.

Any solutions?

Not exactly the solution, but just in case: did you try libinput palm-detection? Could it perhaps help you with your usecase?

Thanks. Not sure about libinput but have **Synaptics Palm Detection (374): 1**

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.
