It looks like that for any session I tried, the most recent being
custom/xterm.

That's what makes me suspicious. Maybe the apps cannot connect to the
xserver. I also tried

| $ env DISPLAY=:1000 xclock
| Xlib: connection to ":1000.0" refused by server
| Xlib: No protocol specified
| 
| Error: Can't open display: :1000

Again, I treid all variations, several different packages, of which
some are from me and reported to work otherwise (???).
