No. > What might cause that? No clue. AFAIK, GTK is not the default, you need to say at least "--with-x-toolkit=yes". > On this system, the string printed by emacs-version is: > "GNU Emacs 28.2 (build 1, x86_64_pc-linux-gnu, GTK+, Version 3.18.9, cairo version 1.14.6) of 2023-01-06" So system-configuration itself already mentions GTK. May I ask why you are asking these questions?
