## Scaling of hdpi displays (high dots per inch)

If working on setups with varying resolutions, configuring e.g. the font
size of a terminal emulator might be difficult.
X11 allows to scale the (entire) display via X resources.
Edit/create the file `~/.Xresources` and add the following line:

```sh
Xft.dpi: <dpi>

# example:
Xft.dpi: 118
```

To apply the changes execute `xrdb -merge ~/.Xresources`.

To make the changes permanent add `xrdb -merge ~/.Xresources` to your
`xinitrc` file, if not present already.
