Mi Mix 2s: black screen

changed the description

added category::device device-category::testing labels

Can confirm not to be working in my replaced screen. Tried sxmo, output of sxmo_version.sh:

Sxmo cat: '': No such file or directory
superd $XDG_RUNTIME_DIR is not set in the environment, this is required.
Connection failure: Connection refused
pa_context_connect() failed: Connection refused
/usr/bin/sxmo_version.sh: line 32: : Permission denied
mmcli 1.20.2
aarch64

Line 32 is the following of /usr/bin/sxmo_version.sh is "$KEYBOARD" -v (KEBOARD variable is unset)

I think that tinydm.log can be also useful:

I am getting this same issue after just installing.

I tried both plasma-mobile and console.

As far as I am aware, the screen is original, it came new in-box with the screen protector thing and I certainly didn't replace it... Maybe it was refurbished. /shrug

Not sure how I can get more info given I haven't set up wifi or anything yet to be able to get at dmesg, etc...

By Joshua Ashton on 2023-02-05T08:26:45

Ah, https://wiki.postmarketos.org/wiki/USB_Internet, nice.

postmarket_dmesg.log

Interesting, looks like basically no DRM stuff came up at all...

bananaphone:~$ drm_info
drmGetDevices: No such file or directory

(/dev/dri is non-existent)

By Joshua Ashton on 2023-02-05T09:25:07

Battery charge reporting is marked as working on the Wiki, yet /sys/class/power_supply/ is empty.

I am guessing there is something much bigger wrong here, perhaps something with the devicetree...?

By Joshua Ashton on 2023-02-05T09:23:33

Maybe someone with a working device can confirm it is still working on the latest PostmarketOS Edge 6.2.0-rc3.

@MollySophia, given you are the maintainer for this device, would you be able to confirm that it's still working? Would like to make sure that this hasn't regressed before spending a bunch of time on something I could bisect.

Thanks.

Hi,

Sorry for my late response. Unfortunately, my own mix2s was broken several months ago, so I cannot test if it's still working.

Looking like the driver for the panel was reverted.

The commit is no longer in 6.2-rc3 after the rebase.

I built my own kernel based on the 6.0.3 using envkernel and the display works fine now the issue does seem to be that the panel driver was reverted.

By Joshua Ashton on 2023-02-06T14:32:02

Hey, could you make your kernel available for download? It looks like postmarketos for Mi Mix 2s has been abandoned

By Mazoch on 2023-02-06T14:32:02

Yes, absolutely! Here:

https://cloud.froggi.es/s/eF5kfPmXFpQqxJZ

It says its 6.2.0 on the package, but it is actually 6.0.3.

By Joshua Ashton on 2023-02-07T14:13:01

I did a build of 6.2.0 with the panel driver re-added:

By Joshua Ashton on 2023-02-07T14:12:47

It works, thank you very much for sharing the kernel :D. There is another problem that I noticed. It seems that the battery driver is also missing, as it indicates 0%. I, unfortunately, can not fix such problems. If you feel like taking a look at it I would be very grateful. I am very happy and thank you again for the work you put in.

By Mazoch on 2023-02-07T14:11:39

I have the same problem and how do you fix it?
