As long as the value of this key is nonempty, the application is
allowed access to DISPLAY and XAUTHORITY environment variables (even
if it's set to false, 0 or the likes). When it's empty, `pkexec` will
still offer a dialog and proceed as usual, but the calling program
(Thunar, in our case) won't be able to start due to not having access
to those two environment variables. The diagnostic message will look
like this:
> thunar: Failed to initialize Xfconf: Cannot autolaunch D-Bus without X11 $DISPLAY
"Won't open" doesn't say much. Do you have the root account set up?
Does `pkexec` have the setuid set: check with `stat -c %A
/usr/bin/pkexec`? Does it show the dialog at least? Can you enter the
password? Can you run non-GUI or other apps with pkexec? Have you
modified the policy file? You may try `apt reinstall thunar`. This
will return your local modifications to defaults.
The policy was added 7 years ago and hasn't been changed since.
Tagging as unreproducible for now.
