Just got an Acer Spin 13, which has a 2K display. When I run Linux apps, the entire application is tiny: fonts, icons, etc. I understand that this is a result of the resolution scaling tricks Chrome OS does, and I discovered that there is an option to "Use Low Density", if you right-click the Linux app icon in the dock. While this fixes the main issue (everything is the right size), it's blurry as heck.

I know that Linux command-line, but haven't had much experience dealing with the GUI side of things. Does anyone know if there's something I can can tweak, some app I can utilize, etc. to help with the HDPI scaling issues? Or, maybe something specific to Chrome OS I don't know about?


On the off chance you haven't found your answer, there still doesn't seem to be a "point-and-click" option available; we've got two CLI options, though:

  1. Set the scaling factor within the app settings/config, or at launch: e.g.,
    atom --force-device-scale-factor=2
  2. Set the HiDPI Scaling via Sommelier config globally or per a given app.

Atom's the only GUI app I'm running and the runtime flag does, in fact, provide me with text that is both not blurry and large enough to read without a magnifying glass, so I didn't devote much time to playing with Sommelier; YMMV.
