(Or maybe I am misinterpreting what you write; I can't figure out with any certainty what the above is supposed to mean.) The reason the text is so small is that the X server (probably) lies to your font rendering library about the actual DPI, so the font rendering library uses a smaller number of dots to render (say) a 12pt font **than it should** at your actual DPI. And so since your dots are closer together than what the font rendering library has been led to believe, the letters appear too small for you to read easily. If the truth was told to the font rendering library, it would know that it need to use more dots than what it is actually using. You don't want lower resolution on your laptop screen. You want the font rendering library to know what the actual DPI is, so that it can draw each glyph with enough dots to make readable text. And just in case you think so, I'm not going on a theoretical rant. I have this working on my systems (Slackware64 15.0 and various Raspbian/Raspberry Pi OS versions). For example, I have told my terminal emulator to use Inconsolata at 10 points. And the text in my terminal windows looks pretty much the same actual size (as measured by a ruler) on my three wildly-varying DPI screens. So I don't need to change my eyewear when going from one screen to the other. If you think it is "of course" that the text is smaller on a higher DPI screen, you are missing the essential point that a 12pt font is defined by a number of points, not a number of pixels. Cheers.
