Everything on Xorg appears to small by default because the default dpi is 96
Attempted Workaround
192 would presumably be ideal for me
I followed the instructions on here https://wiki.archlinux.org/title/X_resources to make that my dpi & applied the other settings listed in the example Xresources file
Complications
I tested this on AwesomeWM
The GUI of AwesomeWM scaled correctly with the new dpi
The GUI of Qutebrowser scaled correctly with the new DPI
Webpages appeared to have a dpi of 96
I will test on Firefox when I get home
The terminal I used (Kitty) went past the bottom of the screen for some reason
Questions
Is there something more or something different I might need to set?
I have a 2560x1440 screen but it’s 24". I set the dpi to 117 in .Xresources. I don’t use XFCE, but I seem to remember that selecting a scale factor of 2 makes the text far too large.
That is not the only choice anymore - in the Settings/Display mini-app, you can choose whatever number makes you happy (or allows you to see). The only gotcha is that the values go the reverse of expected(!) in Display - so try the Custom, and perhaps 0.7 as the value as a ‘test shot’ starting point.
I am running 4K on a 28, and found that wasn’t too bad, although I mostly just kick the DPI up to 120 and increase font sizes (see the EnOS wiki entry for details).
