Using a DE is pretty straightforward but you might be out of luck if you use something like dwm.

Find correct DPI of your display currently used by X server
|
||
|
|
```bash
|
||
|
|
xdpyinfo | grep -B2 resolution
|
||
|
|
```
|
||
|
|
|
||
|
|
This si probably the correct value. If not, you can calculate it by converting your screen size to inches and dividing the resolution by display length.
|
||
|
|
```bash
|
||
|
|
xrandr | grep -w connected
|
||
|
|
```
|
||
|
|
|
||
|
|
{{% center %}}
|
||
|
|
{{% figure src="/img/xrandr.png" title="The output on my machine" alt="Output of the last command" %}}
|
||
|
|
{{% /center %}}
|
||
|
|
|
||
|
|
The above block spits your screen resolution and physical size. Now divide it by display length in inches.
|
||
|
|
|
||
|
|
Create/modify the file `~/.Xresources` and append the following line (replace 96 with your DPI)
|
||
|
|
```
|
||
|
|
Xft.dpi: 96
|
||
|
|
```
|
||
|
|
and have it processed by the startup file (like .xinitrc)
|
||
|
|
```
|
||
|
|
xrdb -merge ~/.Xresources
|
||
|
|
```
