Sorry you're having a problem. It looks to me like your system might be configured to use Wayland for graphics
[+0.47s] DEBUG: Seat seat0: Creating display server of type wayland
[+0.51s] DEBUG: Session pid=3026: Running command /etc/X11/Xsession /usr/bin/labwc-pi
If this is the case, this would most definitely be your problem. The second paragraph of the README states:
" NOTE: VNC only works on X11-based systems. More recent Ubuntu releases, such as 22.04 and later, appear to use Wayland by default. I have not had the time to sort out how to make this project work on Wayland-based systems. "
If you want to use this VNC technique you need to switch your desktop to X11 using raspi-config.
Yes, the README could use a bit of spiffing up.
update: it works but the colors are all wrong. no wallpaper either. do i need to change the bitrate maybe ?
