[Nexus 4 Android Development] 7wells:
@voron00

Here is my first log, taken with Android 7.1.2 = LOS 14.1-20200420-NIGHTLY-MLQ-mako from @milaq, where Slimport works:

EDIT: replaced by log, where I know the timepoint of unplugging, too:

Notes:

1. No TV or other type of display was connected at the other end of the adapter/cable.

2. The Slimport adapter has an extra mini USB socket for external power supply, so the Nexus 4 can be powered in parallel, but I do not use it for these logs.

3. I always restart the Nexus 4 and wait a little bit after establishing the ADB via network connection, so everything can settle for several moments.

I will repeat logging with a display attached in order to see if/which difference this makes.

The logs from your LOS 16.0 and 17.1 (where Slimport does not work on my Nexus 4) will follow - again without and then with a display attached. My Nexus 4 device might freeze, so I am not sure yet, how much I will get from logcat.

Thanks for your patience and support!

Now again with LOS 14.1, but this time with a display connected to the other side of the Slimport adapter:

Now I am going to format, wipe, and flash LOS 16.0 (and - as before - Magisk 20.3, but no OpenGApps or any other stuff) and will repeat the above steps.

This might take a while, because I have to take care for some other stuff as well. So please bear with me... ;)

Now with LOS 16.0, with no display attached to the other side of the Slimport adapter (the Nexus 4 does not freeze):

Interim summary so far:

When no display is connected to the Slimport adapter, the log reads the same for LOS 14.1 and LOS 16.0.
