+Searching the we led me to [[https://askubuntu.com/questions/538993/gtk-message-failed-to-load-module-overlay-scrollbar|Ask Ubuntu]]. In my case, the setting was the environment variable //GTK2_MODULES//:

+Following the basic idea, I followed the answer linked above and found
+<code bash>
+~ $ cat /etc/X11/Xsession.d/81overlay-scrollbar
+# This file is sourced by Xsession(5), not executed.
+if [ -z "$GTK2_MODULES" ] ; then
+        GTK2_MODULES="overlay-scrollbar"
+else
+        GTK2_MODULES="$GTK2_MODULES:overlay-scrollbar"
+fi
+export GTK2_MODULES
