Tested in Debian 12 and it does not open display

[monnoval]

Hello, I recently tested this in the current Debian 12 KDE Plasma and I'm getting cannot open display. I tried to use --external and still does not work.

$ eval $( gp-saml-gui --gateway --allow-insecure-crypto --clientos=Windows vpn-at-somewhere.tech )
Looking for SAML auth tags in response to https://vpn-at-somewhere.tech/ssl-vpn/prelogin.esp...
Got SAML REDIRECT, opening browser...

(gp-saml-gui:154893): Gtk-WARNING **: 14:05:36.352: cannot open display:

Can anybody help me debug further this problem or maybe guide me where to look for logs. Thank you!

I'm getting cannot open display.

That's because your DISPLAY environment variable is unset. The error message is actually cannot open display: $DISPLAY.

I tried to use --external and still does not work.

You will most certainly not get the same error message when using --external.

What error message do you get in that case?
