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:

Same problem here. The crash occurs while launching slim, so you end up with a login prompt in text mode

Let's wait until tigervnc gets updated in Arch repositories, so we can test again the 10-vnc.conf issue.

Re: tigervnc with 10-vnc.conf causes Xorg Segmentation fault

Unfortunately it's still happening with git version:
https://aur.archlinux.org/packages/tigervnc-git

I'll report the issue to GitHub:
