Yesterday I’ve installed i3wm-gaps just for fun, knowing that last time I tried it on my Retina MacBook Pro ti was completely unusable due to the Retina display.
This is changing today.
Since both GTK+ 3 and QT 5 now have good HiDPI support, setting
Xft.dpi: 192 into the
.Xresources file makes sure all applications written using these two frameworks will scale properly on the display.
You have to set the i3 font to exactly 2 times your desidered size, for example “Droid Sans 10” will become “Droid Sans 20”.
Here you can find my i3 configuration for this machine.
