X11VNC starts and stops continuously
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.
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?
Running xauth list returns
pi@fullpageos:~ $ xauth list fullpageos/unix:0 MIT-MAGIC-COOKIE-1 eabf04bbe75459048011cf86d412d5e3
pi@fullpageos:/home $ x11vnc -findauth XAUTHORITY=
I guess this is not supposed to be blank?
Is there anything else I can do? I haven't been able to do anything about it so far...
I have had a lot of trouble with X11VNC. I removed it and replace by realVNC and now it works perfect and powerfull.
@romankysely do you think its worth to switch to it? what binary are you using?

Hi Guy, thx for question and interest. Yes, I do. I have very good experience. I mentioned at closed issue https://github.com/guysoft/FullPageOS/issues/571 already. When I use your image I immediately remove x11VNC and instlall realVNC instead. Yes, they have Cloud solution paid but if you maintain your list of connections localy, than is it free.
@romankysely what commands do you use to install it? We could add it here: https://github.com/guysoft/FullPageOS/blob/devel/src/modules/fullpageos/start_chroot_script#L121
We could even add an optional switch like with x11vnc and have realvnc the default if its indeed better, which I think it has potential to be. Might have to figure out how to generate the password.
Thx. Yes, good idea but I am not programmer. I am afraid to interfere to your code. I am ChatGPT codewriter :-)) Instalation commands: sudo apt install realvnc-vnc-server # Instalation RealVNC server sudo systemctl enable vncserver-x11-serviced # run after boot sudo systemctl start vncserver-x11-serviced # run realVNC server
Diagnostics: dpkg -l | grep realvnc # check instalation package realVNC sudo systemctl status vncserver-x11-serviced # check running realVNC
Login and password is the same as during install OS puted.
