This feels like a dumb question: how do you tell Plasma Mobile to power off the handset?

At the moment the only option seems to be to press the power button and have the screen go blank. But even then it appears that the backlight is on (from certain angles the screen appears to glow). So I want to power the handset off completely when I'm not using it, to be sure.

Note that I did try `shutdown` in Konsole, but it returned an error.

Which device is this? Clicking Power button should turn backlight off.

Hello, bshah. It's good to hear from you. I was a little worried that Plasma Mobile had been abandoned. (And I really, really want an alternative to the commercial ecosystems.)

The handset is an LG Nexus 5X. In a well-lit room it did look like the screen had turned off, but in a dark room it became very much evident that the backlight was still burning away behind the black pixels. (You could hold the screen to a wall and see it light up the wall, albeit gently.)

Because of that and a few other quirks (camera was a test card and some white noise; adb could not talk to handset while running Plasma Mobile; could not setup wi-fi; frequent lock-ups and crashes; and eventually the handset ceased booting into Plasma Mobile altogether) I did remove Plasma Mobile from the handset. But given that I know Linux always takes a while to size up and assimilate new hardware, and given the ambition of the project, I'm not at all surprised that there's more work to be done. I'm looking forward to future announcements about new builds to be tested.

I know nothing about hardware, but if you happen to need small, focused Java libraries or tools to be produced to aid in Plasma Mobile development, then I might be able to assist.
