Mount Nexus 5x via USB

I'm trying to mount one of the new nexus 5x phones on my laptop via mtp. When I plug it in, nautilus recognizes it as a nexus 5x and an option appears on the left. However, when I click on it, the area where files normally appear is blank even though there should be files there, and I'm unable to create files. Interestingly, lsusb returns:

Bus 004 Device 002: ID 8087:8000 Intel Corp. 
Bus 004 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 003 Device 002: ID 8087:8008 Intel Corp. 
Bus 003 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 001 Device 003: ID 5986:055c Acer, Inc 
Bus 001 Device 002: ID 0cf3:3004 Atheros Communications, Inc. 
Bus 001 Device 023: ID 18d1:4ee1 Google Inc. Nexus 4
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

Oddly, lsusb thinks it's a nexus 4, while nautilus correctly sees the 5x. Maybe it's just not supported yet? I found the following in my syslog:

I'm using Ubuntu 15.04 on a Eurocom Electra 2.

Also, can somebody with more reputation than me create the nexus-5x tag? thanks @KGIII

Edit: I've tried mounting with mtpfs; errors are similar to what I saw in the logs, and the mount doesn't happen.

$ mtpfs nexus5x/

I have also attempted to download the newest libmtp from source, but it still does not appear to work--I say appear to because I'm not entirely sure what should happen. I tried mtp-files:

libmtp version: 1.1.10

Device 0 (VID=18d1 and PID=4ee1) is a Google Inc (for LG Electronics/Samsung) Nexus 4/5/7/10 (MTP).

OK.

Solution 1:

Actually, it's working!

When you connect the N5X (screen unlocked) to your Linux box the N5X will default to USB charging (a security feature I think). The N5X will appear in your Linux file manager but won't show internal storage. If you pull down the notification shade on the N5X you should see it showing USB charging. If you select that you should be offered other options, including MTP for file transferring, PTP for photo transferring and MIDI.

Thanks to davharuk.

EDIT I definitely agree with the comments. COMPLETELY confusing. I was too.
