Can the dpi for the graphical debugger be configured

[peter.ludemann]

How to set font size on graphical debugger?

Yes, editing ~/.config/swi-prolog/xpce/Defaults font.scale did the trick (almost). I had to remove the leading ! (having forgotten the conventions for X11 config files). I’ll have to do some more fiddling to get the debugger help displaying at a size I like. @jan - if the debugger help is available in the SWI-Prolog online documentation, I couldn’t find it and “grep” only found me xpce/prolog/lib/trace/pltracer.hlp.
