I'm running Android 6.0.1 on my phone and Kubuntu 14.04 on my laptop. I also have a 32GB micro SD card in the phone. I've tried to set that card up as internal storage, and the prompts when I inserted the card seemed to indicate that I was doing just that. But on the phone in Storage and USB, the SD card is shown a a eeparate entity, and Internal Storage shows just 5 GB. MTP access shows only internal storage, not the SD card. How can I get access to the SD card from the laptop?
I should note that before doing operations on the phone, I took the SD card out of the phone and inserted it into the laptop. There I set up an MSDOS-type partition table on the card and then created a single (primary) partition with a FAT32 format. Having done that, I moved the card back to the phone, where it seemed to be recognized, and seemed to give me the choice of using it as internal storage. But that doesn't appear to be what actually happened, since MTP shows internal storage only and I can't copy any significant amount of data to it over the USB cable.
