Xvnc does not work with GDM anymore

[jttoivon]

I used to be able to run stand-alone Xvnc server and connect to it using GDM. But this stopped working after I upgraded to OpenBSD 7.5, and now that I have upgraded to 7.6 it does not work either.

I use TigerVNC. In my /etc/inetd.conf file I have the following line:

localhost:5901   stream   tcp nowait nobody  /usr/local/bin/Xvnc Xvnc -inetd -query localhost -once SecurityTypes=None -localhost -geometry 1860x1020 -Log *:syslog:100

I have added in my /etc/gdm/custom.conf file the lines:
[xdmcp]
Enable=true

Then I start GDM and inetd:
rcctl start gdm
rcctl -f start inetd
After which I try to connect to the OpenBSD box:
xtigervncviewer -via 192.168.122.218 localhost::5901
The command opens the VNC window, but it closes immediately.

The relevant lines from /var/log/messages and the /var/log/gdm/127.0.0.1:1-greeter.log are attached.

Xvnc is started automatically, but it looks like GDM is trying to start Xorg, and fails, instead using the Xvnc server.

Note that I have also installed Xorg in addition to Xvnc, and it starts automatically after starting GDM.

Any ideas how to fix this?

I managed to fix this by removing relevant packages and then reinstalling them. Below are the commands I used.

doas pkg_delete tigervnc gdm gnome-session xfce
doas rm -rf /var/db/gdm
doas rm -rf /var/log/gdm/*
doas rm /etc/gdm/custom.conf
doas /usr/sbin/userdel _gdm
mv .vnc old.vnc
doas syspatch
doas pkg_add -u
doas rm -f /var/db/colord/mapping.db /var/db/colord/storage.db
doas rm -rf /var/sasl2/* /etc/dconf/db/* /etc/dconf/profile/*
doas rm -f /var/db/upower/history-*
doas pkg_add tigervnc gdm gnome-session xfce
doas rcctl start messagebus
doas emacs -nw /etc/gdm/custom.conf
doas rcctl restart gdm
doas rcctl -f start inetd

The problem probably was not in the .vnc directory, since after I renamed it back, it kept on working. Most likely the problem was in those removed files, since I had previously tried everything else unsuccessfully.
