How to reproduce the issue:

1.Install tigervnc 1.12.0-3
2.Create file /etc/X11/xorg.conf.d/10-vnc.conf according to https://wiki.archlinux.org/title/TigerV … y_directly

Section "Module"
Load "vnc"
EndSection

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

3.Reboot and Xorg crashes always:
