I have just installed RuneAudio+R e4 on my USBBridge Signature/Katana DAC, but when I activate Chromium nothing is displayed on my HDMI 1920x1080 display from Waveshare (https://www.waveshare.com/wiki/5.5inch_HDMI_AMOLED).
I followed the Waveshare advice and I added the following in my config.txt:
hdmi_timings=1080 1 26 4 50 1920 1 8 2 6 0 0 0 60 0 135580000 3
But it does not help: when I check the status of Chromium using a ssh console, I can only see that it is not started. When I type "startx", I get the fatal error "no screens found(EE)". As I have no programming knowledge, I would be grateful if someone could help me to work out this issue (my screen works on Moode and Volumio, so I assume that it is linked to some missing configuration in RuneAudio).
Thank you in advance
