Thnks a lot @hakerdefo

Hi. I'm just new in this community but I've using Linux for years and I hope I will for ever. The question is that i work like a teacher and I can't use the projector(monitor) and the TV MultimediaScreen that we have in the classrooms since I have my laptop with UbuntuStudio 22.04LTS. The TVMultimedia Screen is an APLX-65 of Promethean. In tthe webside they have as a downloads the ActivDrivers only for Ubuntu20 .04(Focal).
