I have a bunch of RPi 3B+ that are set to "Desktop Autologin GUI as user XYZ" using the raspi-config tool. The RPis all run headless, but need the desktop GUI up and running for remote desktop sessions using DWService. This works fine, except for one of those RPis, which does not allow remote access to the (virtual) screen.
Here's what I figured out so far on the particular RPi that has this problem:
The SD card is writable, so the GUI autologin setting should be stored on the SD card after adjusting in
raspi-config(I tested this by writing a file, and the file was still there after rebooting the machine).There is 23G of free space on the SD card. This should be more than enough for the desktop environment to run (that's the first thing that came up when I googled for this problem).
If I log in via ssh, I can't find the GUI login session (the other RPis show the x11 session as expected):
water@pemcell-A:~ $ loginctl
SESSION UID USER SEAT TTY
1 1001 water seat0 tty1
3 1001 water pts/0
2 sessions listed.
- The X server log file shows that the X server terminated:
water@pemcell-A:~ $ tail /var/log/Xorg.0.log
[ 20.649] (II) SELinux: Disabled on system

[ 20.773] (II) Initializing extension DRI2
[ 20.937] (II) Server terminated successfully (0). Closing log file.
Overall, this looks like the GUI environment tries to start at boot, but for some reason it stops working. However, I have no clue what is going on, and where to look for solutions. Can someone shine some light on this or tell me where to look?
P.S.: please don't tell me to reinstall the whole system, which might wipe out the issue. I have already thought of that, but it would be a lot of work to set up and configure all the software running on this RPi, so I am hoping to avoid that.
Edit-1: Here's a diff of the /var/log/Xorg.0.log files on a "good" and on the "bad" machine (I don't really know what this stuff means, but maybe it's useful to someone who does):

Edit-2: Looking at /var/log/lightdm/lightdm.log I found the following bit:
[+0.40s] DEBUG: Launching process 907: /usr/share/dispsetup.sh
[+0.40s] DEBUG: Process 907 exited with return value 1
[+0.40s] DEBUG: Seat seat0: Exit status of /usr/share/dispsetup.sh: 1
[+0.40s] DEBUG: Seat seat0: Stopping display server due to failed setup script
So I tried looking at the /usr/share/dispsetup.sh script, but found that the file does not exists on the "bad" machine (it does on the "good" machines). This explains why the GUI environment will not start at boot.
Now, the new question is: what would be a reasonable explanation for the missing dispsetup.sh file, and what would be a suitable fix?
lightdm, the display manager, or else the desktop environment, presumably the latter with autologin but I cannot say for sure) doesn't last long. There may be an error about that in the system log.
