Emacs Asked by Ed Sabol on November 10, 2021
I recently switched to CentOS 7.7, KDE 4.x, and Emacs 26.3. Previously, I was using GNOME and a much older version of Emacs. Before, whenever I opened Emacs, the titlebar of a lone Emacs window was emacs@hostname. Now, it’s emacs@hostname <@hostname>, which seems less than desirable. I can’t figure out if the issue is with Emacs or KDE. Any ideas as to what is wrong here and what I can do to get it back to emacs@hostname?
Emacs controls its frametitle via variable frame-title-format.
So you could change the value of that variable temporarily, to get an idea weather or not KDE is manipulating it somehow.
I.e. do M-: (setq frame-title-format "foobar") return and check the new title of the frame.
If the frametitle is now foobar <@hostname>, then KDE changes it and you have to look into KDE settings or KDE applets, plugins or whatever to modify the behavior.
If it is now just foobar, then it is controlled entirely by emacs. Have a read at EmacsWiki: Frame Title to see what options you can use to change it to what you like.
