In the systemd service, I believe that Carlos was setting $0 to emacsd for the following effect:
$ xprop -name emacsd@$HOST | grep WM_CLASS
WM_CLASS(STRING) = "emacsd", "Emacsd"
This is because desktops use the StartupWMClass in the .desktop file to match which windows are associated with which .desktop file, and we want a daemonised Emacs to be matched to emacsclient.desktop rather than emacs.desktop.
Consequently, now that this section of the patch has been reverted, the following line remaining in emacsclient.desktop makes no sense:
StartupWMClass=Emacsd
Perhaps we can find a different way of setting the WM_CLASS X11 property?
Alternatively, if we merge the two .desktop files, this issue goes away. There is currently some discussion of doing this for other reasons on emacs-devel.
IĒve unarchived bug 37847 in order to add this comment, and hope that that isnĒt a breach of etiquette. IĒll happily raise a new bug if thatĒs preferred.
