How to disable the touchscreen in Ubuntu 21.04?

cn flag

I faced a problem after a couple of days that my malfunctioned touchscreen was on unexpectedly, despite setting MatchIsTouchscreen "off" at /usr/share/X11/xorg.conf.d/40-libinput.conf

How to make it disabled just like Ubuntu 20 and the older versions?

There is no Ubuntu 20, what version are you running?

You have edited the question to say 21.04 and that link says 20.04 not sure that is any clearer.

You didn't get my question, it's about Ubuntu 21.04, the touchscreen disabling issue starts with that version. I was wondering if it can be disabled like 20.04 or older versions. That link is about Ubuntu 20.04 which you said it doesn't exist.

So after hours of searching a solution to that is keep that configuration MatchIsTouchscreen "off" and to make Xinput runs by default again to apply that configuration.

To disable Wayland:

  1. open the file: sudo nano /etc/gdm3/custom.conf
  2. uncomment (remove # from): WaylandEnable=false

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.
