Hi,
To reproduce :
1. Start `emacs -q --daemon`
2. Start a frame with `emacsclient -c`. At this point, X clipboard
access works fine and I can copy/paste between emacs and other
applications.
3. From Thunar (file manager from xfce), right click a file and `Open
with` emacsclient (/usr/bin/emacsclient), creating another frame.
At this point, X clipboard access is broken: I cannot copy/paste
between emacs and other applications.

If you're using X, you shouldn't be using PGTK. The support provided by
the real X port is miles ahead of what GTK can offer.
That aside, I suspect emacsclient is causing Emacs to open a second
display connection, which causes clipboard access in PGTK to be disabled
due to a GTK bug.
What does (x-display-list) evaluate to in the buggy Emacs, after you
create the other frame which causes the bug?
Thanks.

Is --with-xinput2 supposed to work well without PGTK ? I run into a
separate issue with key bindings that makes it unusable without.

Indeed, (x-diplay-list) originally reports (":0.0"), and after the
second frame is created, (":0.0" ":0").
If the bug is with GTK, can you think of any workaround on my end ?

Thank you.

`--with-xinput2' does nothing on PGTK, but it enables the use of the X
Input Extension on X, which brings support for modern input devices to
the X port. (And that support is supposed to work better than PGTK,
since you get touchpad gestures and touchscreen support, both of which
aren't available in PGTK on X.)
Please report the separate issue as a bug, if it hasn't been fixed
already on master.
XInput 2 support will eventually be enabled by default, so it's vital
for it to get a lot of testing.

I see you're launching /usr/bin/emacsclient -- emacsclient from a PGTK
build differs from one from a different build, so are you sure it's the
right emacsclient binary?

I can't, sorry.

Will do.

Yes, it's the right binary.
The issue must be specific to the way Thunar starts the application.
I've just checked that it works fine when using Nautilus (the GNOME
file manager) instead.

Thanks, then we should add it to etc/PROBLEMS. (But please try to find
a workaround first.)
