I am looking for a way to have a single use computer for video conferencing. I want to use the Vidyo desktop client. I want to be able to turn on the computer and it boots directly to the Vidyo Client with no options for the user to use the computer for anything else than Video Conferencing with the Vidyo App.
This seems like a Support question, so I’ll refer you to the support venues for it. This particular site is more about coordination and discussion of the Ubuntu project. Sorry.
For Ubuntu’s excellent support venues, see https://community.ubuntu.com/t/finding-help/712 . There are quite a few single-use or “kiosk” questions (and answers) there.
