LCD advice please my Volumio friends

You just need to install the Touch Display plugin, no driver required.

Be aware that there is possibly a problem switching off the backlight when the display is rotated by 90 or 270 deg. as reported by @buma

[PLUGIN] Touch Display

Hello there, new to the board, but not to Volumio. I built a stand-alone headphone music server with a Raspberry Pi 4 and a DSI monitor (WaveShare 4.3" capacitive touch display) using the latest build of Volumio (2.917) and the Touch Display plugin (1.3.0), and no other plugins. Everything works just fine except for the Screensaver Setting - it won’t turn off. This was a rebuild of an earlier project using the same RPi but with a different screen. The screensaver worked fine on the older scr…

set to 90 degrees and now the problem is also present, it does not turn off, the screen flickers 2x briefly, so it does make an attempt to go out, but it does not go through. by the way the touch is at 90 degrees outline.

I also tried 270 degrees, same problem. then there is indeed a difference compared to the Raspberry Pi Foundation touchscreen. Shame.

got to test it a little earlier. okay a fresh install of volumio2 on a raspberry pi 3b version 1.2. touchscreen set to 90 degrees and 20 seconds timeout and no screensaver on. and here also the same problem after 20 seconds the screen dims slightly also at 270 degrees it does not work. only difference is that now the touch is good.

Waveshare suggested a hardware modification to solve the issue:

@gvolt @michel8166 so, Waveshare replied… sorta [waveshare-response]

I don’t know if this works and if Waveshare has done this themselves on the current PCB layout.
