I've been using ubuntu 18.04 since I got this Dell laptop in 2018. I don't have any dual thing, just ubuntu. Yesterday suddenly sound is gone and only Dummy Output is shown in settings, but I still had wifi. Now wifi and bluetooth (I never use bluetooth anyway) are also gone - "no wifi adapter found" in settings. What is happening to my system? More importantly how can I fix this (please gear simple, straightforward answer for non-tech person)
