I wanted to set up the diskperf plugin on my HP ZBook Studio G3. I have Linux installed on my second SSD, which is put in an nvme slot. I tried to set the disk-to-be-monitored to /dev/nvme0, /dev/nvme0n1 and /dev/nvme0n1p2, but all of them show "Device status not available" when I hover over the panel plugin.
Same here (message is "device statistics not available"). Thinkpad T470.

OK, this is actually fixed in 2.6.1. See Bug 13281.
That should indeed fix it. I'll wait till Ubuntu 18.04 LTS comes out before I can verify that it works (this app is stuck at version 2.5.5 in Ubuntu 16.04), but since this report is duplicate, it can be closed :) *** This bug has been marked as a duplicate of bug 13281 ***
