Manjaro Stable update 3-14-2020 breaks touchbar

[treymerkley]

some reason, when I updated, this isn't working anymore. I uninstalled and reinstalled using both git and AUR, but neither gets it to load. I was on 5.4, but neither 4.19 or 5.5 work either. Neither does rebuilding with DKMS.

EDIT:

Thanks!

[roadrunner2]

Thanks for the info. Unfortunately, the dmesg output you gave above is for the keyboard driver, which is separate from the touchbar driver. So can you show me the output of the following commands:

dmesg | egrep -i 'apple-ib|ibridge'
lsusb -t
ls -l /sys/bus/hid/devices/*/driver

[treymerkley]

Sure, thank you so much for helping out.

Hmm, that lsusb -t output is very odd: there should be another 3 devices listed as children of the last item. For reference, this is what I see on my system:

    |__ Port 3: Dev 2, If 3, Class=Human Interface Device, Driver=usbhid, 480M

Also, the fact there are no hid devices is problematic.

All in all, this looks like some USB issue on your system, but it's hard to tell what. The fact that the iBridge device does seem to be detected at one point according to the kernel logs, but then later lsusb -t isn't showing it (and there are no hid devices), makes it sound like there may be some other error that is causing the iBridge device to go away. Can you look through your kernel log and see if there's anything weird related to USB in there?

[roadrunner2]

Oh, two more things: what machine/model are you on? And what is the output from

ls -l /sys/bus/usb/devices/

[treymerkley]

That is pretty weird. Does this help at all? I'm on a Apple Macbook Pro 15.4” Touch Bar A1707 - Core i7 - 3.1Ghz.

Quick additional comment: I tried to connect to my laptop via bluetooth as well, but it says that no bluetooth device was found. I know that's mostly unrelated, but it might help to know.

[roadrunner2]

That is pretty weird. Does this help at all? I'm on a Apple Macbook Pro 15.4” Touch Bar A1707 - Core i7 - 3.1Ghz.

Ok, that's the MacBookPro14,3 then.

And this confirms the iBridge USB devices are truly missing (there should be four 1-3:1.x devices there).

Since you say this happens on different kernels, I'm starting to suspect something is weird with the T1/iBridge chip itself. Dumb question, but have you completely powered off the laptop since this problem started?

[roadrunner2]

Quick additional comment: I tried to connect to my laptop via bluetooth as well, but it says that no bluetooth device was found. I know that's mostly unrelated, but it might help to know.

Assuming you're talking about kernel 5.5, see the bottom of Dunedan/mbp-2016-linux#29.

[treymerkley]

Yeah, I've completely power cycled it, too. It shouldn't be a hardware thing; I dual boot, so I checked the Mac side before posting and both work there.

Bluetooth is broken on all of the kernels for me, and I noticed the issue on 5.4, but if there's a fix I can wait for 5.5-9. rEFInd was autoselecting 5.5, my mistake.

Something else, when turning off the machine there is often a stop job that can last up to a minute and a half.
It's worth noting though that it isn't every time, and it isn't a predictor of whether the touchbar will work.

[treymerkley]

Does this help? I was looking through dmesg.

The Touchbar just flickers and turns off.

I am on Macbook Pro 13,3 running Manjaro with kernel 5.5.9 + patches from @aunali1

@mflor35 add it to the update thread on Manjaro, too. Someone who works on it might have insight if everyone with the problem mentions there.

[roadrunner2]

@mflor35 Thanks for your info. First of all, this furthermore appears to confirm it's truly a Manjaro (or least Linux) issue, not a one-off h/w problem or something. Second, your dmesg output and your comment that it flickers (I presume you meant "touchbar", not "trackpad") are very interesting: it looks like something is actively causing the iBridge USB device to be removed/disabled.

Can one of you show me the output of

sudo grep . /sys/bus/usb/devices/usb1/1-3/*
sudo grep . /sys/bus/usb/devices/usb1/1-3/power/*
sudo grep . /sys/bus/usb/devices/usb1/1-3/port/power/*
ls -l /sys/bus/usb/devices/usb1/1-3/driver

Also, I agree, getting some Manjaro devs involved would be good, as it appears to be something recent and particular to that distro that is causing the problem (something related to USB).

[treymerkley]

Sure!

[mflor35]

@roadrunner2 yes! I meant touchbar.

@treymerkley I'll add my info to the manjaro forums
