I am somewhat of a novice with all of this, but I have a Waveshare 5" screen that I cannot seem to get the touchscreen to work since recent Volumio update (currently running 2.692). I have followed and attempted the directions from several (all?) of the other threads, but ultimately end up with it not working. I have the following added to the
hdmi_cvt 800 480 60 6 0 0 0
And added file
sudo nano /etc/X11/xorg.conf.d/99-calibration.conf
MatchProduct "ADS7846 Touchscreen"
Option "Calibration" "208 3905 288 3910"
Option "SwapAxes" "0"
The screen display works fine, and the web interface works. The hardware includes a HifiBerry MiniAmp and a Mausberry Circuits switch (both installed, and work without issue).
