3.5 inch GPIO display - Black Screen

[Darkside1984]

Hello everybody!

I’ve installed Volumio in my Raspberry Pi 2 Model B with a non-branded 3.5 inch GPIO display (XPT2046) . After first boot, initial config and Touch Display installed and enabled, I’ve followed the steps here and alternatively here. In that process apparently there’s no errors but when I reboot and Volumio starts the display keeps in black (white initially and black when it starts).

The Volumio web shows this errors:

Error connecting to the Xserver
Error modifying /etc/X11/xorg.conf.d/95-touch_display-plugin.conf: Error: Command failed: /bin/echo volumio | /usr/bin/sudo -S /bin/sed -i -e ‘/Option “TransformationMatrix”/d’ /etc/X11/xorg.conf.d/95-touch_display-plugin.conf [sudo] password for volumio: /bin/sed: can’t read /etc/X11/xorg.conf.d/95-touch_display-plugin.conf: No such file or directory

I’ve tried the same process with various Volumio versions (latest, lower than 1.55,…) and the same weird final. In some of the attempts, I connect the RPI to an external monitor via HDMI and I can see the Volumio interface (even with the tactile feedback when I touch the GPIO screen).

The screen works perfectly with other OS (Raspbian) but I can’t get it to work with Volumio.

What am I missing?

Thanks in advance.

This seems to be related to this forum post. I think the issue could be closed as reinstalling the plugin solved the problem.
