cannot get ABS_X info, Invalid argument

I've managed to correctly compile the library for Android 9 and pushed the androidvncserver binary to the device but when I run it in a root shell I get the following output:

Initializing framebuffer device /dev/graphics/fb0...
xres=1920, yres=1080, xresv=1920, yresv=2160, xoffs=0, yoffs=0, bpp=32
Initializing keyboard device /dev/input/event3 ...
Initializing touch device /dev/input/event1 ...
cannot get ABS_X info, Invalid argument

I saw similar issues but they were closed.
I need a simple vnc server binary that I can run at device boot, I've also tried the droidVNC-ng app which works fine but even with the checkbox set to run on boot it doesn't start upon booting up the device and I have to manually open the app.
I'm open to any kind of suggestion, what I'd like is a binary that I can run at startup.
Thanks

androidvncserver is very much just a demo and uses legacy APIs, so there's no guarantee things are working as intended. I recommend to use droidVNC-NG, we should fix start-on-boot for that one together, so feel free to file an issue there (need logcat output!).

Dupe of #184 anyway, which I'll re-open.

@bk138 is droidVNC-NG the only option or is there a simple binary I can start upon boot? Also, how would I grab the logcat upon booting? I don't think adb logcat would work in this case but I'm not sure, also do you happen to know which filter can I use to just see the droidVNC lgos? I've tried multiple of them but I just get not results. Here's some output I'm getting when simply opening the app and clicking start

Grabbed just by running adb logcat

[bk138]

@f0lg0 you can just run adb logcat and reboot the device, make sure it adb reconnects on device boot, if not, you have to do adb logcat again manually. Needs a bit of fiddling but I know for a fact that one can get early boot logs with that. Let's discuss over at droidVNC-NG.
