After years of prolog use, today I finally decided to give the built-in editor a try. Unfortunately, it is simply unusable for me in its current state, and I’m not sure what to do about it. The editor is so tiny that it is impossible for me to read anything. I suspect it’s not really designed to wo…

Turns out there was a much better option for setting all font sizes at once: font.scale: 5.0 Still got a tiny mouse though.

After a lot of sitting really close to my monitor I think I got it. ~/.config/swi-prolog/xpce/Defaults can be supplied with font information, including default font sizes. A default config can be generated in this location by going to Edit->Editor Preferences (second menu from the left, then seco…

I could have sworn I searched discourse before asking :slight_smile: clearly not as there’s been several topics on this. Apologies!

One obvious question is: maybe the default values should be changed? (And don’t feel bad about searching for an answer and only finding it when someone points it out – that’s happened to me a few times.)

On my Chromebook, I removed the display.dpi setting in ~/.config/swi-prolog/xpce/Defaults and replaced my font.scale: 1.2 with font.scale: @display?dpi?width/100 image.scale: when(@display?dpi?width > 150, 2, 1) Is there a way to find out what the default values for display.dpi, etc. are? BTW, fo…

[image] peter.ludemann: Is there a way to find out what the default values for display.dpi, etc. are? Normally, the server tells the screen dimensions in pixels and mm. The pixels are typically correct, but it seems that it often does not manage to get the size in mm correct. I think tha…

[image] jan: Normally, the server tells the screen dimensions in pixels and mm. Is there an “easy” way to see the values from the server? (That is, the values of display.dpi, font.scale, etc if there is no override value in the Defaults file)
