I’m surprised to see not many people mention about it. I use Ubuntu 18.04, MATE desktop, tried tweaks, and used the font setting tools within qjackctl, but cannot change a thing. I have to use an amplifier to read the character in the gui screen. Hope somebody can help me out of this, so that I can start recording use Ardour 5.
I haven’t been able to create a working session yet, thinking that I’ll get there with larger readable characters.
