X11VNC starts and stops continuously

[Z3r0shin]

What were you doing?

Using a Pi3 A+, in portrait mode (commenting out the various dtoverlays in the config.txt file), it shows splash screen, connects to wifi correctly but keeps starting and stopping the X11VNC service continuously until the screens goes blank save from a rapidly blinking underscore in the top left cornerf for about 5 minutes before rebooting with the watchdog.

What did you expect to happen?

For it to load the webpage as it did before I've rotated the display

What happened instead?

See description above.

Was there an error message displayed? What did it say?

It didn't, except for the watchdog timer that rebooted the pi

Version of FullPageOS?

0.14.0 nightly

Screenshot(s) showing the problem:

If you are building FullPageOS - provide a build.log that is created for the build

I am new to compiling programs and stuff, else I'd remove the X11VNC since I don't need it and add the --no-memcheck flag to the chromium start script to prevent the "under 1g ram" chromium warning from popping up.

[Z3r0shin]

It seems the X11VNC is dependant on something that the dtoverlay provides and therefore goes exactly as its service file asks it to do : on_failure every 2 seconds.
I have no idea what I am doing.

Can you run and share the output of

systemctl status x11vnc.service

?
It might tell us what the error is.

Seems its something to do with Xauth? It can't find the .Xauthority file?

[Z3r0shin]

Running xauth list returns

pi@fullpageos:~ $ xauth list
fullpageos/unix:0 MIT-MAGIC-COOKIE-1 eabf04bbe75459048011cf86d412d5e3

[Z3r0shin]

pi@fullpageos:/home $ x11vnc -findauth
XAUTHORITY=

I guess this is not supposed to be blank?

[Z3r0shin]

Is there anything else I can do? I haven't been able to do anything about it so far...

No idea
