So I’m still a big fan of the Manjaro I3WM community distro, it’s probably my favorite operating system of all time. However, now that I’m running a 4k Monitor, there have been a couple things that I’ve had to figure out. That last issue that I have had is a problem with the on-screen notifications. First, I had to figure out what the heck was supplying the notifications (it’s a program called Dunst). Second, I had to do a little research on why it wasnt accepting the DPI settings I had set using the xrandr command, and the .Xresources file. It turns out it’s a known bug. However, I was able to find a workaround.
To fix this, you’ll need to open up your favorite editor (I used nano) and change the dunstrc file.
From here change the “global” font setting (on my 28″ 4k screen, I doubled the font size, which seems about right):
font = Cantarell 20
Once your done, you’ll need to either restart, or kill dunst, and start it back up. Once that’s done, you should be able to read your notifications once again!
