Perhaps you are running CDE in a virtual machine and I am running CDE on a laptop.

  I have a patch that lets you build 2.4.0 on FreeBSD i386, it is not a general patch, it is just applied only when building for that platform.

    Can I write a quick guide to installing CDE 2.4.0

      The patch mentioned in the message can be applied with "git apply" before the build.
      
      https://sourceforge.net/p/rhubarb-pi/code/HEAD/tree/trunk/pkg/cdesktopenv/patches/8e4de154957ff3230bd18ae4110a2e7c1b9db87d.FreeBSD.i386
      
      So do the clone of the git repository with the flag --branch 2.4.0 to get the correct code for the patch to be applied to, apply the patch with
      
      $ git apply ../8e4de154957ff3230bd18ae4110a2e7c1b9db87d.FreeBSD.i386
      
      Then proceed with the build as you normally would.
      
      I have my own scripted build process which applies the patch automatically when it matches the commit hash. So it works best when you specify a specific tag or branch, eg
      
      $ ./package.sh 2.4.0
      
      Alternatively you could try the package I created.

        Thanks for the patch. Installed CDE 2.4.0. Only I can not enter through dtlogin "login incorrect"
        
        The big change from 2.3.2 to 2.4.0 is the use of the pamd modules. These may require additional configuration
        
        I have just tested with my build, I use the dtlogin init script from the contrib directory

        CDE builds on top of openmotif and has "dtwm" to replace "mwm", with CDE I suggest it is better with using the CDE window manager.

        After several attempts to log in with dtlogin, I had to reinstall FreeBSD 13.0 because the rc.conf error was thrown at boot time. I need to add dtlogin_enable = "YES", but I couldn't login. Moreover, I have already configured CDE. Installed programs, created program icons. It all takes a very long time.

        The two ways do run CDE are...
        
        dtsession, when already logged in as a user
        
        dtlogin, which starts as root and provides complete login and authentication
        
        in neither scenario should MWM be involved at all.
        
        So if using dtsession then that should just be talking to the X server and taking control with dtwm
        
        If using dtlogin, then that should be starting X, running the dthello/dtgreet and then passing control to dtsession+dtwm
        
        So before moving to using the dtlogin rc script, should be able to start with a root login at the console and run /usr/dt/bin/dtlogin -nodaemon, if you can't get past that stage then the rc script will not help
        
        It looks like a pamd problem, with NetBSD I had to add a dependency on pam-pwauth_suid, but I could not see an equivalent for FreeBSD
        
        Also, make sure you have SSH server running, then if locked out of console you get back in over the network

        I installed CDE 2.4.0a using your patch. Prior to that, CDE would hang on startup after logging in. Dtlogin does not work now. I am a user, not a developer

        CDE is not in the FreeBSD repository (https://www.freshports.org/x11/cde). I don’t think that if the FreeBSD committers didn’t want to run CDE on the i386, then there’s a problem.

        The hang on login is normally caused by portmapper/rpcbind not running or the hostname not in /etc/hosts
        
        I am running the straight 2.4.0 build, I have published my binaries here
        
        I avoid running anything that is not a formal release, so I build from an explicit tagged commit from git, and then publish any patch I needed to make to get it going.
        
        The autoconf builds are not ready in my opinion

        I would suggest go back to the 2,4.0 version and solve the hanging. If the hanging was occuring it was after the authentication was succesful. The hanging is a known problem and hopefully can be addressed with making sure that rpcbind is started and your hostname is in /etc/hosts against 127.0.01.

I found that I didn't have the /home/user/.dt/dtwmrc file. I think I don't have any files yet. Therefore dtlogin starts, but authorization fails. I copied the dtwmrc file to /home/user/.dt.

That sounds wrong. dtlogin should be running as root, not as an already logged in user. The authentication should occur before the contents of $HOME are examined. The user should not need any specific CDE configurations setup before behand, it should all be initialised on first run by dtsession.

I start FreeBSD, enter my username and password. And then I start CDE via startx. I am running FreeBSD. Dtlogin starts. I enter my username and password, but there is no user data in the system.

That is not how it is designed to be used, there is nothing gained by trying to login again when you are already logged in. If you are already logged in as a user you should be using dtsession to establish the desktop environment with the X server. And dtsession will expect a blank X server with no existing window manager running as it will want to use dtwm

  Actually using startx works great and is fine for starting CDE... Especially if you do not enable a GUI login manager like dtlogin. My VM's generally run this way. Then I can login normally and just run
  
  startx /usr/dt/bin/Xsession
  
  when I want to fire up CDE.

      Very pleased you are now up and running.
      
      In terms of terminology, startx is not doing a login. You are already logged in. Startx is starting an X windows session. When you use CDE that is ultimately a desktop managed by dtsession which in this case is invoked by /usr/dt/bin/Xsession. CDE already uses OpenMotif so you should not be trying to use mwm in addition, dtwm is a superset of mwm, and many components of CDE require dtwm to be the window manager to function properly.

        I find it difficult to express my thoughts in English. My native language is Russian. Why am I logging into FreeBSD, but through dtlogin it gives an error. This means that the window manager has no user data. Perhaps there is no file. This thought came to my mind when I discovered that the dtwmrc file was missing. That's why I asked

        Very pleased you are now up and running.
        
        In terms of terminology, startx is not doing a login. You are already logged in. Startx is starting an X windows session. When you use CDE that is ultimately a desktop managed by dtsession which in this case is invoked by /usr/dt/bin/Xsession. CDE already uses OpenMotif so you should not be trying to use mwm in addition, dtwm is a superset of mwm, and many components of CDE require dtwm to be the window manager to function properly.

Yes it is a mystery why the dtlogin from boot does not work. I have CDE 2.4.0 working on FreeBSD 13.0-RELEASE on ARM64, I386 and AMD64, all happily with the dtlogin process as I have described using the dtlogin-init sequence. Yes typos in /etc/rc.conf can be disaster, hence why testing by logging in at the TTY console as root then manually running /usr/dt/bin/dtsession and using SSH to look at the log files is a good first step.

  I couldn't run CDE 2.4.0 without your patch. CDE hangs after logging in on a blue screen. There were a lot of errors when compiling CDE, but CDE started up and works through startx. Perhaps dtlogin does not work due to compilation errors. In fact, the fact that I ran CDE 2.4.0a makes me very happy. thanks for the help
