I have been using Ubuntu since 2015 with my Dell Vostro 3500 laptop (main device) as well as other PCs. Up through 21.10, Ubuntu always found the nVidia graphics hardware and gave me the opportnity to add correct driver. Unity 22.04 finds the Broadcom WiFi, butnot the nVidia. Ubuntu 22.04 LTS could not even find Broadcom. How do I make my Dell laptop find the nVidia hardware? Thank you,
John
