Help getting gtk or qt pinentry dialog forwarded over ssh connection

[Arjun]

Hi Werner

I do know that I need to enable ssh X11 forwarding, and have tested it with ForwardX11 and ForwardX11Trusted 
on (-X and -Y on the command line). Unfortunately, pin entry always defaults to tty. I fully trust the machine (it's mine). xfd does say "no font to display".

In fact, if I ssh in, and run

    /usr/bin/pinentry-gtk-2
    getpin

I do get an X11 window to type my pin into. When I type in 

    getinfo ttyinfo

it does say "gtk-2". However, the logs I attached say that when I run

    gpg --decrypt ...
    
The GETINFO flavor command on pinentry gives 

    gtk2:curses

This is the reason I'm seeing a curses pinentry when I try to gpg --decrypt something. I don't know how to get my gpg-agent to give me an X11 pinentry. 

Best
Arjun
