Hi,

Self-reply.

I found the solution after launching gpg-agent with --debug-level
advance option.   In a nutshell, gpg-agent doesn't seems to support
Xwayland.   It works with Xorg, but not with Xwayland.   So I changed
/etc/gdm/custom.conf so that gdm always launches Xorg instead of
Xwayland and the problem has gone.


Thank you!!
