I had inherited these lines in .Xresources from way back: Emacs.FontBackend: ftcrhb,xft,x Emacs*font: -adobe-Utopia-normal-normal-normal-*-*-*-*-*-*-0-iso10646-1 After the update/build, emacs refused to start in GUI mode, -- emacs -nw worked, and it displayed the font backend error when started as emacs under X. I worked around the problem by commenting out the emacs.font line and it started with Adobe Courier. This morning, I updated the font backend line as suggested by you, and now I get over 3,000+ fonts -- and uncommenting the Adobe Utopia line does not cause the error. Could we update the News file with details on what font backends are now recommended? >>>>>> On Mon, 20 Jan 2020 14:52:34 +0100, Robert Pluim said: > Robert> If all else fails, can you run 'strace emacs' with your normal config > Robert> to see if itʼs loading some site-specific configuration files?
