trouble running papertty.py about papertty HOT 7 CLOSED

turns out I had forgotten to enable spi. I am now however getting this issue:
vncdotool.api.VNCDoException: [Failure instance: Traceback (failure with no frames): <class 'twisted.internet.error.ConnectionRefusedError'>: Connection was refused by other side: 111: Connection refused.

The VNC error messages could be made a bit more helpful. What command/settings are you using for the VNC server? Is the password correct?

Hi
I'm trying to build a ebookreader with a pi0 and a 9.7inc waveshare epaper.
I probably do something wrong in the installation, but I don't find where.

I create de virtualenv with :
mkvirtualenv -p /usr/bin/python3 -r requirements.txt papertty
No error appears in the windows

I create a connection with :
(papertty) pi@raspberrypi:~/Documents/github/PaperTTY-master $ vncserver -geometry 1200x825 :3
There isn't any error end it's end with
Fichier journal : /home/pi/.vnc/raspberrypi:3.log Nouveau bureau : raspberrypi:3 (192.168.1.22:3) (papertty) pi@raspberrypi:~/Documents/github/PaperTTY-master $

But when I launched
sudo ~/.virtualenvs/papertty/bin/python3 ./papertty.py --driver it8951 vnc --display 3 --password supAPass --sleep 0.1 --rotate 90
The script end with
Timeout to server localhost:3
(I tried with my pi password and with my root password in place of supAPpass)

It appened after the line
client.refreshScreen()
in papertty.py

I already tried to forced the ip adress and the display, if i write a wrong adress or display I have another error, so I think it's ok

I also check the vncserver by connecting to it on my smartphone, it work's fine, but I noticed that there is a message on the desktop
GDBus.Error:org.freedesktop.PolicyKit 1.Error.Failed: An authentication agent already exists for the given subject

I also tried to do the same without the virtualenv, it give the same error (timeout...), the only difference is that I have a warning at the begining
:0: UserWarning: You do not have a working installation of the service_identity module: 'cannot import name 'verify_ip_address' from 'service_identity.pyopenssl' (/usr/lib/python3/dist-packages/service_identity/pyopenssl.py)'. Please install it from <https://pypi.python.org/pypi/service_identity> and make sure all of its dependencies are satisfied. Without the service_identity module, Twisted can perform only rudimentary TLS client hostname verification. Many valid certificate/hostname mappings may be rejected.

After 'vncserver -geometry 1200x825 :3' I launched 'x11vnc -display :3' and now I have my desktop on the epaper
I also tested without 'vncserver -geometry 1200x825 :3' and directly 'x11vnc -display :0', it works

One thing to keep in mind is that the VNC server's password is separate from your user's (pi) or root password. Of course, you can set the same password but VNC typically might support only a maximum length of 8 and is not secure to begin with. Usually when starting up the server the first time it prompts for a password to set (and stores it in ~/.vnc/passwd or so, so that you don't need to set it again the next time).

I'm not exactly sure what you achieved with running both vncserver and x11vnc but does it work the way you wanted now?

I'll close this now - if you're still having trouble, please reopen the issue or create a new one.
