Exactly.
Fortunately, many file managers (like
Nemo on my EndeavourOS/Cinnamon) have an option to
disable automounting removable media, see screenshot. This works nicely here: The device shows up, the DE plays the "Connect" sound, but it
doesn’t get automounted by the file manager and Calibre can do its work (Auto-connect, use, Eject device, etc.).
If you wish to use the device
outside Calibre, you can normally mount/unmount it using the file manager.
If using
gvfs (GNOME-based DEs), you can also disable this only for MTP: In
/usr/share/gvfs/mounts/mtp.mount:
Code:
[Mount]
Type=mtp
Exec=/usr/lib/gvfsd-mtp
AutoMount=false
Since you’re using KDE, maybe Nautilus has an option like this, too, or you find something in the KDE settings.
