Why are you unable to type numbers? Is there something unusual about your keyboard layout (or locale settings, etc.)? Are you using the Arena key remapper mod? I've never used that "panel" you photographed...is that a built-in feature of DOSBox?

When people ask you to share the output, it's best to actually copy-paste the output (not just describe it). There are specific technical things we're looking for. So, can you copy-paste it?

After reading your responses to other comments, I think I understand, but that's quite strange. So, when you run DaggerfallUnity.x86_64, I assume you see a window that says "Welcome to Daggerfall Unity" and "Please set the path to your Daggerfall game files", right? And you see a bunch of system folders, including home, but when you go into /home/[username] you see nothing there? If you go into other folders, such as /etc, I assume you see some folders and files there? Perhaps share a screenshot if there's anything I'm missing.

My first guess: Maybe you've done something strange to the permissions on your home folder. But that's a long shot. Please copy-paste the output from the following command (but feel free to delete anything that might be considered "sensitive info"):

ls -la ~
