Help and Support

Hi everyone !

So i’m facing two problems :

  1. First, i’ve successfully installed my new HDMI touchscreen (https://www.kubii.fr/ecrans-supports/2193-ecran-tactile-133-hdmi-lcd-ips-1920x1080-kubii-3272496011052.html) on my raspberry 4 (2 GB). I’m using volumio v3.198 on it.
    Everything works fine except that all around the screen there is some black band.

There is no problem when i touch near the center of the screen

but as soon as i touch the edge of the screen there is some gap between my finger and the cursor.

i’ve tried to calibrate the screen that way :

volumio@volumio:~$ DISPLAY=:0.0 xinput_calibrator Warning: multiple calibratable devices found, calibrating last one (ILITEK ILITEK-TP Mouse) use --device to select another one. Calibrating standard Xorg driver "ILITEK ILITEK-TP Mouse" current calibration values: min_x=0, max_x=65535 and min_y=0, max_y=65535 If these values are estimated wrong, either supply it manually with the --precalib option, or run the 'get_precalib.sh' script to automatically get it (through HAL). --> Making the calibration permanent <-- copy the snippet below into '/etc/X11/xorg.conf.d/99-calibration.conf' (/usr/share/X11/xorg.conf.d/ in some distro's) Section "InputClass" Identifier "calibration" MatchProduct "ILITEK ILITEK-TP Mouse" Option "MinX" "1805" Option "MaxX" "63245" Option "MinY" "2270" Option "MaxY" "63498" Option "SwapXY" "0" # unless it was already set to 1 Option "InvertX" "0" # unless it was already set Option "InvertY" "0" # unless it was already set EndSection volumio@volumio:~$ sudo nano /etc/X11/xorg.conf.d/99-calibration.conf

I’ve copied the information, reboot, but nothing have changed.

Any idea how to remove those black band and enhance the precision of my aiming ?

  1. I have a second problem regarding shairport.
    I’ve installed shairport on an old rapsberry 1 with raspbian. It works perfectly with itunes but i can’t find it with volumio or any streaming service (like spotify).
    I’ve suscribed my free trial of the premium account in order to enable the multiroom and streaming on shairport.
    Any idea ?

Thanks a lot, i hope my poor english is understandable.

Did you already put

hdmi_group=2
hdmi_mode=82
hdmi_cvt 1920 1080 60 6 0 0 0

into your “/boot/userconfig.txt”?
