Hello guys, here is the solution
HOWTO make EDM fonts working in Raspberry Pi4 (8GB) - Raspian OS:

1. Enable the high quality scalable fonts in the default font path:
sudo -s
cd /usr/share/fonts/truetype/liberation2
mkfontscale
mkfontdir

2. Check the current fontpath:
xset -q

NOTE:
The fontpath must contains:
/usr/share/fonts/truetype/liberation2:scaled,
/usr/share/fonts/X11/75dpi:unscaled,/usr/share/fonts/X11/75dpi,built-ins

3. Install 75 and 100 dpi fonts:
sudo -s
apt-get install xfonts-75dpi
apt-get install xfonts-100dpi

4. Give 512MB for the GPU from system preferences:

sudo raspi-config

7 Advanced Options [Enter]
A3 Memory Split    [Enter]
512                [Enter]
OK                 [Enter]
Finish             [Enter]
OK                 [Enter]

5. Use another way to add the liberation2 font to the default font path:
cd /usr/share/X11/xorg.conf.d
sudo vi 50-fp.conf

Add the following content:

Section "Files"
    FontPath "/usr/share/fonts/truetype/liberation2/:scaled:pri:10"
EndSection

That's all Folks
 Thank you John Sinclair for your help!

Subject: EDM fonts on Raspian ...

Hello all,

I tried to used Raspberry Pi 4 (8G RAM) to act as OPI for some tests, but, when loading the EDM screens, the fonts became ugly. I tried some different configurations and different fonts installation without success. Using MEDM it works well, the fonts are nice and the screens are the same on the original server.

Has someone experience EDM in Raspian? (They are becoming promising with the new 8G Ram model).

Thank you

  Ernesto
