#263308 — Hardware Misses on MacBook Air M1 2020

[Multipart message — attachments visible in raw view] — view raw

I have an M1-chip 2020 MacBook Air on which I have dual-booted with Debian
12 initially, then "upgraded" to sid (in hopes of getting better hardware
support). It has several hardware ... glitches, and my google-fu is failing
me in finding solutions. I'm hoping someone here can help.

First, the good news: Basic functionality works fine. Both Gnome and Plasma
work on both X11 and Wayland; graphics are crisp (albeit tiny, until I use
the GUI's size-mag feature to bump it to about 175%), and both wired and
wireless networking work, even with our certificate-based authentication
wireless network, that I could never get to work with a version of Debian
around 9 or 10 or so (but the connection is a little daunting for the
average Joe). I can't really speak for Sleep/Hibernation, as I haven't had
it running that long (UPDATE: It just announced it was automatically
suspending as I was typing this; I suspect it'll wake when I try it in a
few (UPDATE: Yes, it woke up instantly, perhaps too instantly?)), but
screen time-out/wake-up works fine. Audio via my Bluetooth ear buds works
great.

Now the bad news:

- keyboard backlight. Ag, how I need this in my usually-dark computing
environs!

- display brightness. It's either full-on or full-off. This is a much more
minor concern.

- audio. As mentioned above, audio works fine via Blluetooth (watched an
interesting Adam Savage video about a $13 USB-c cable vs Apple's $130
version; I can't believe I'm saying it, but I think the Apple version might
actually be worth that), but I can't get a peep out of the built-in
speakers. Everything *seems* to be in order; alsamixer sees both the
Pipewire device and the native Mac sound device; volume controls move up
and down (or left/right); there's just never any sound. Not even from
"speaker-test" after I've killed X/Wayland/gdm3, although "speaker-test"
(as a non-root user) looks like it's working. It acts like the speakers are
muted, but I can find no way to unmute them. When I run "speaker-test" as
root, it complains that the service (server? device?) is not
running/available? (Sorry; don't recall the exact message at the moment.)

- Though not really a hardware matter, thought I'd mention this for anyone
who wants to try Debian on their MacBook Air M1; when I updated to Sid,
apparently the Mac got "confused", and when I tried to boot back into
macOS, the system insisted on having my decryption password (which I guess
is normal, now that I think about it, 'cause FileVault 2 does that also,
just ... differently, so that I didn't recognize it), but then it also
insisted on a Recovery Key being typed in (like when Bitlocker locks you
out of Windows when it thinks the hardware has been tampered with).
Thankfully I had that key available, or it would have been a wipe/reimage
(or perhaps worse, the way Apple has locked things down of late).

So if anyone has any help for these issues, especially audio and the
keyboard backlight, I'm all ears.

Thanks!

Have you checked alsamixer for MM?
Can you check which chip it is with lspci and which kernel module is
loaded?

What does dmesg say?

Out of curiosity, does Debian 12 support the M1 NPU (Neural Processing 
Unit) ?

[Sorry; sent to Jeremy only the first time; meant to send it to the list.]

Sorry, no clue. Don't even know how I'd ascertain that, but if you can give
me a simple test, I'd be happy to try it for you.

Have you considered just running Debian in a Virtual Machine until hardware
support matures.

I started to look at that yesterday, but apparently VirtualBox doesn't
support the Mac's M1 chip, and QEMU looked a bit daunting on the Mac, so I
gave up on that pursuit for now. The issues I'm currently having seem less
painful to me than getting a VM up and running on the M1 Mac.

On Mac most people use Parallels for virtual machines.
