After I upgraded to 19.10, my Xubuntu system works fine EXCEPT that some apps, like the browser and applications that want to set a folder to save files, don't see the external drive, as if they don't have permission or something.
If I try and view the drive contents myself, I can see it and access it via the Thunar file manager of Xubuntu, with no problem; but when I try to save files from within installed apps, they don't even see the drive in the /media folder.
The owner of the drive and group are both set to the user and not root. Nothing about this came up when I searched this site, and there's not a lot of answers to this specifically on Google. I have no idea what to do; how may I troubleshoot this?
