UNSOLVED All fonts too small on start-up
Sometimes when I reboot (sudo reboot now), the MM (autostarting with PM2) starts up with fonts that are way too small. I’ll go through the reboot procedure again and it often, but not always, starts with the correct fonts. Every once in a while I’ll have to reboot a third time. Once the MM is up and running it’s very stable. Has anyone experienced this and solved the problem? Can anyone suggest a place to start to diagnose and solve this problem? Thanks!
