TigerVNC libvnc.so "No password configured for VNC Auth"

I'm trying to expose my local display

I do have /etc/X11/xorg.conf.d/10-vnc.conf and it contains

Section "Module"
Load "vnc"
EndSection

Section "Screen"
Identifier "Screen0"
Option "UserPasswdVerifier" "VncAuth"
Option "PasswordFile" "/root/.vnc/passwd"
EndSection

In ~/.local/share/xorg/Xorg.0.log I can find that I'm loading it but it looks like neither UserPasswdVerifier nor PasswordFile get used.

[    14.929] (II) LoadModule: "vnc"
[    14.929] (II) Loading /usr/lib/xorg/modules/extensions/libvnc.so
[    14.949] (II) Module vnc: vendor="TigerVNC Project"
[    14.949] 	compiled for 1.21.1.6, module version = 1.0.0
[    14.949] 	Module class: X.Org Server Extension
[    14.949] 	ABI class: X.Org Server Extension, version 10.0

[    15.026] (WW) modeset(0): Option "UserPasswdVerifier" is not used
[    15.026] (WW) modeset(0): Option "PasswordFile" is not used

/root/.vnc/passwd exists

-rw------- 1 root root    8 jan 13 16:05 passwd

Running it using vncserver@.service also works but I'm having trouble launching some graphical applications that way.

Trying to connect this way returns

 CConn:       Authentication failure: Authentication failure: No password
              configured for VNC Auth

There're two major problem here:
1. the options seems somehow ending up w/ the modesetting module, please post the entire xorg log
2. ~/.local/share/xorg/Xorg.0.log very strongly indicates a rootless server meaning you won't be able to access /root/.vnc/passwd ( https://wiki.archlinux.org/title/Xorg#Rootless_Xorg )
