dpi or font size being automatically set somewhere - hidpi screen

Hi All,

I think this is a feature but I'd like to override it...
The feature, something is detecting I have a high res screen and automatically increasing my font size.

That's a really niice feature, only issue is when I plug an external screen and use that as my primary display, my font sizes are huge and xrandr command to set the dpi are being ignored.

Perhaps it's not a DPI setting but a font setting, because only my fonts in gtk and kde4 apps are large, while fonts in kde5 apps (with a broken look/theme) are fine.

Using i3, there is mention that i3 has automatic HiDPI support, perhaps that's what's tinkering with my DPI. How would I override it then?

https://wiki.archlinux.org/index.php/HiDPI

Primary display is 1920x1080 on 12.5" screen. I use  xrandr --auto --dpi 96 command when just using this display.
At work I use a 21" display also 1920x1080 res. I use xrandr --output HDMI1 --mode 1920x1080 --right-of eDP1 --dpi 96 when using both displays.

~ xdpyinfo | grep -B 2 resolution
screen #0:
  dimensions:    1920x1080 pixels (508x285 millimeters)
  resolution:    96x96 dots per inch

Any ideas?

Not sure what was adjusting my fonts, but I managed to resolve it by install plasma-desktop, open systemsettings5 and tick force fonts DPI to 96.

Hardly ideal (but at least its something for now), as I now have additional KDE applications installed.
