Touchscreen not working/not being recognized 20.04 (Screen permission denied)

cn flag

Trying to get my touchscreen working on Ubuntu 20.04 but not finding much information about it.

When I run xinput I don't see it mentioned.

Run lsusb, and it doesn't appear

I tried to follow the Ubuntu guide but when trying to find the serial connection I kept getting permission errors.

screen /dev/ttyS0
[screen is terminating]

Screen

/dev/ttyS1

bash: /dev/ttyS1: Permission denied

Sudo Screen

/dev/ttyS1

bash: /dev/ttyS1: Permission denied

I added myself to the appropriate group also so I do have permission.

So I can't tell where it's connected to and continue trouble shooting.

  • Kernel 5.8.0-63 Generic

Any help would be appreciated

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.
