[GUIDE] Waveshare 11.9"/7.9" DSI LCD Display Configuration for Volumio 4

Help and Support Guides
11

Hey @Mustang65,

Thank you for the additional details. The hardware setup is clear, but to investigate why Volumio 4 behaves differently from Volumio 3, diagnostic data is required.

Please provide:

  1. Log link from http://<volumio_IP>/dev - paste the URL it generates after submitting
  2. Actual file contents - SSH into the device and run:
cat /boot/userconfig.txt
cat /boot/cmdline.txt
  1. Verification command outputs:
fbset
cat /proc/cmdline | grep video
cat /sys/class/drm/card1-DSI-1/status
ls /sys/class/drm/

“I followed the guide exactly” and actually following the guide exactly are often two different things - the previous user also believed they followed it correctly but had missing section markers and extra parameters. The verification outputs will confirm whether the configuration was applied as intended.

The fact that Volumio 3 works and Volumio 4 does not suggests either a configuration difference or a kernel/driver behavior change between versions. The logs and outputs above will help identify which.

Kind Regards,
