I have an Android 9 phone (Google Pixel XL) which does not show up when I connect it to my laptop via USB. I have Ubuntu 18.10.
I have enabled developer options and USB debugging. When I connect my phone, I can choose "File Transfer" from the phone, but the phone still doesn't show up on Ubuntu.
I was able to authorize the computer from the phone, and the phone shows up when I do adb devices
, but I still don't see the phone in my file manager.
