I help manage a small fleet of thinkpads with Xubuntu 16.04 that are used for giving workshops.
When a user attaches a USB key, I need Thunar to automount the USB with read and write permissions for that user (non-root). Presently, it is automounting as read only. I've tried at least 3 different usb keys. They all show lock icons on files inside the usb key.
Basically, I need the participants of our workshops to be able to plug their USB key and “drag and drop” files from a local folder into their USB key.
Edit: I've tried this using 3 different usb keys in 3 different file systems (ntfs, ext4, and fat32) and results were the same.
Interestingly, if in Thunar, I select the file: right click -> Send to -> usb , it works as intended.
The challenge is that most of our workshops participants are children who are learning to use computers, so the less steps, and the more intuitive the better. That's why I really would like to get drag and drop to work.
