Here's a transcript of a session on our corporate server:

/home/REDACTED[0]$schroot --chroot=chroot:lmi_bookworm_4
/home/REDACTED[0]$
/home/REDACTED[0]$Xvfb :1 -screen 0 1280x1024x8 &
[1] 103327
/home/REDACTED[0]$_XSERVTransmkdir: Owner of /tmp/.X11-unix should be set to 
root
/home/REDACTED[0]$ls -ld /tmp/.X11-unix
drwxrwxrwt. 2 mm53451 REDACTED 16 Nov 13 14:49 /tmp/.X11-unix
/home/REDACTED[0]$kill 103327
/home/REDACTED[0]$
[1]  + done       Xvfb :1 -screen 0 1280x1024x8
/home/REDACTED[0]$sudo chown root:root /tmp/.X11-unix

Oops, I had forgotten that, while I'm a sudoer on the
redhat host, I never did find a way to use sudo in a
chroot on this server. Let's rule out this problem:

/home/REDACTED[1]$exit
/home/REDACTED[1]$sudo su -
Last login: [date redacted]
/root[0]#ls -ld /srv/chroot/lmi_bookworm_4/tmp/.X11-unix
drwxrwxrwt. 2 REDACTED REDACTED 6 Nov 13 09:50 
/srv/chroot/lmi_bookworm_4/tmp/.X11-unix
/root[0]#chown root:root /srv/chroot/lmi_bookworm_4/tmp/.X11-unix
/root[0]#ls -ld /srv/chroot/lmi_bookworm_4/tmp/.X11-unix
drwxrwxrwt. 2 root root 6 Nov 13 09:50 /srv/chroot/lmi_bookworm_4/tmp/.X11-unix
/root[0]#exit

Now, back into the chroot as our normal user:

/home/REDACTED[0]$schroot --chroot=chroot:lmi_bookworm_4
/home/REDACTED[0]$cd /opt/lmi/src/lmi
/opt/lmi/src/lmi[0]$Xvfb :1 -screen 0 1280x1024x8 &
[1] 104245
/opt/lmi/src/lmi[0]$echo $DISPLAY
:0.0

At first, I tried using that value of $DISPLAY, ":0.0",
which is wrong:

/opt/lmi/src/lmi[0]$DISPLAY=:0.0 wine /opt/lmi/bin/wx_test --ash_nazg 
--data_path=/opt/lmi/data --test log_error
0009:err:winediag:nodrv_CreateWindow Application tried to create a window, but 
no driver could be loaded.
0009:err:winediag:nodrv_CreateWindow Make sure that your X server is running 
and that $DISPLAY is set correctly.

Instead, we want the DISPLAY value specified in this command:
  Xvfb :1 -screen 0 1280x1024x8 &
and that seems to get us farther:

/opt/lmi/src/lmi[0]$DISPLAY=:1 wine /opt/lmi/bin/wx_test --ash_nazg 
--data_path=/opt/lmi/data --test log_error
Assertion '"Assert failure"' failed
(incorrect bitmap type in wxBitmap::GetRawData()).

^C%

The string "incorrect bitmap type" doesn't occur anywhere in
this mailing list's two decades of archives. Vadim, have you
any idea what could cause that?
