The most seamless way I connect my phones to a computer is using the AirDroid app:

AirDroid relies upon WiFi connectivity, not a USB cable so there's no need to mess with any configuration changes to your tablet or Linux PC. You just need to have your tablet and your PC connected to the same local network to detect and interact with each other. All you need is the AirDroid app on your tablet, and a web browser on your PC. This works with Linux, Mac, or Windows desktops and laptops, and any web browser (i.e. Firefox, Chrome, Edge, Safari, Opera, Brave, etc.) so you don't need to mess with any USB-centric settings like MTP, PTP, nor mass storage, nor any driver or utility installs that might be limited to a specific operating system and its version.
Basically you would just start up the AirDroid app on your tablet, take note of the IP address and port number in the local network section (i.e. 192.168.1.6:8888), and set your tablet aside. Go to the Linux PC, type in that IP address

ort number exactly as is into your browser, and a window will show with a modified simulation of your tablet. There are various remote access icons and pertinent to your query options to transfer files/folders from or to your PC. (A notable caveat is AirDroid really, really wants you to sign up with an account with them, allowing you not just local network connectivity but their online storage/access too. But the app is fully functional with no limitations if you just rely upon local network access. I've been using the app for years now and have never bothered to sign up for an account. So be sure use the provided local network IP address all the time. Well, unless you do want the option of using their online storage service.)
