Hi Massimo,
I have just created a new SD card imaged with the new _bookworm_20240317 image. When the system boots it returns to the login prompt, rather than starting QLCPlus.

When I login locally (with HDMI display) and try and run QLCPlus I get the following error regarding QT ...

Linux pi2024 6.6.20+rpt-rpi-2712 #1 SMP PREEMPT Debian 1:6.6.20-1+rpt1 (2024-03-07) aarch64

qt.qpa.xcb: could not connect to display
qt.qpa.plugin: Could not load the Qt platform plugin "xcb" in "" even though it was found.
This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem.

Aborted

I have built the image/SD card twice now with the same result.

Have I missed something?
Happy to provide diagnostics if you tell me what is required.

Many thanks,
Nick

Thre's an issue when no display is connected. See this
viewtopic.php?t=17150

In case the display is present, the error you see is usually caused by bad SD card. Try another one
