Hey @vol-pi5,
Your userconfig.txt matches my guide for Pi 5 + 11.9" display exactly, and the cmdline.txt parameters are correct. However, there is one problem and several diagnostic questions before I can investigate further.
Problem: Pi Imager customisation was applied during flashing
Your cmdline.txt contains this parameter:
cfg80211.ieee80211_regdom=DE
This is not part of the Volumio image. It is injected by Raspberry Pi Imager when the OS Customisation dialog is used during flashing. The Volumio flashing guide explicitly states: do not apply any customisations or modifications when writing the image.
Reference: [Beginner's Guide]: Flashing Volumio OS to a microSD Card
The customiser may have altered system files beyond cmdline.txt that are not visible from the boot partition. This could be contributing to your blank screen, but I need diagnostic data to confirm.
Diagnostic information nedded:
- Kernel command line as seen by the system (this is the most important item - it shows firmware-injected parameters not visible in /boot/cmdline.txt):
cat /proc/cmdline
- DRM display connector state:
ls -la /sys/class/drm/
cat /sys/class/drm/card*-HDMI-A-*/status
-
Which HDMI port is the display connected to? Port 0 is the one nearest to the USB-C power connector. Port 1 is the other one. The guide requires port 0.
-
Is the Touch Display plugin installed? If yes, what is its status - enabled, active, or failed? The Touch Display plugin is required for the Volumio UI to appear on the local display. Without it, only console output is rendered.

A previous user in this thread (@Jay_Calvert, post #5) had the identical fbset symptom - 320x1480 instead of 1480x320, black screen with backlight on. In that case, /proc/cmdline revealed the firmware had injected a conflicting video= parameter that disabled the display output before the user’s own parameter was processed. The /proc/cmdline output will confirm whether the same thing is happening here.
Kind Regards,
