Waveshare 7.9inch HDMI LCD install?

Help and Support
21

Hi
I run volumio on a raspberry 4 which has two HDMI ports.
Is it possible to use the ultra wide-screen for PeppyMeter and the other Display (TV) to show volumio normally?

22

Hi … I have the same doubts. did you get any reply or solutions?

hello i have this Waveshare 7.9inch Capacitive LCD HDMI Touch Control Panel working , but there is no touch function … mmm is that normal or is there more to be installed to use the touch function… ?

Is the display’s USB port connected to the Pi? If so, please try another USB cable for that connection. If that doesn’t help, connect to Volumio via SSH. From there execute

ls -al /dev/input

and post the output.

Also post the output of

cat /var/log/Xorg.0.log

Please also provide some additional information about your system:

What is the Volumio version?

What Pi model are you using?

first output is
volumio 1
second output is
volumio@volumio:~$ cat /var/log/Xorg.0.log

There are two USB connections, one for power and the other for touch control. You may need to try a different USB cable for touch control.

29

Have you tried the button on the back yet?
I have the same thing when I switch to picoreplayer.
