In bookworm, trixie or noble?

Can someone confirm that xwayland is working in the other wayland desktops in armbian? I can't make it work in labwc

Share your DTS. It is the most challenging part of this. We can customize, based on SBC model.

Start with this DTS and change the GPIO for your OPIZ3 https://github.com/raspberrypi/linux/blob/rpi-6.12.y/arch/arm/boot/dts/overlays/piscreen-overlay.dts Or start with your DTS and change the "compatible" line to "compatible=waveshare,rpi-lcd-35" and copy the other parameters of piscreen-overlay.dts if needed Let us know if it works

Getting video acceleration is realtively easy in bookworm, but making it work in Trixie would be newsworthy

It all depends on the GUI apps you want to run. Web browser: at least 4GB Your own Python GUI app: 1GB 16GB storage is fine. "A more advanced build framework" only refers to the laptop you use to compile your own Armbian OS... it doesn't refer to the SBC where you will run it.

Yes, CONFIG_TINYDRM_ILI9486 is the kernel module for that model of LCD with DRM. There's another thread explaining how to use it. I think you can use udev rules to force SPI LCD as /dev/fb0 and HDMI as /dev/fb1 always.

I noticed this problem a long time ago, but now I feel it is important to fix it: I get a slim black bar on the left side, and a portion of the pixels on the right get "cropped" because they don't fit in the LCD display area? I get the left 2 pixels of the screen "cropped", so in console, the first left-side are always missing the left pixels. Do you get the same in your LCD? Do you know a way to fix it? I am talking about this LCD: RED PCB LCD https://www.aliexpress.us/item/3256802847521952.html?

In that case, dont try my solution: it is for the red ili9341. If you search ili9486 threads in this forum, that same blue LCD is ili9486... so you were wrong in calling it ili9341 in the first place If you have time, find another solution to get you a DRM frambuffer (instead of a classic FB). Then you can enjoy smoother animations and video. Regarding displaying boot messages to the LCD, instead of HDMI. I don't know, but it may be because your HDMI is /dev/fb0 and the LCD is /dev/fb1 Will you use X11?

Try this solution for the orange pi zero LTS, which is the same chip as the opiPC, but change the pin definitions to what you have. Do you have a 480x320 ili9341? Which one is it?

If anyone in interested in a lightweight wayland desktop, inspired by openbox, you should try labwc. In orange pi zero 3, we need to stay in bookworm to get video acceleration, so this guide helps build labwc in bookworm As a greeter, I chose pi-greeter, because it is the lightest login manager I could setup, without any X11 https://github.com/robertojguerra/opiz3-labwc-setup I am open to read any improvements, or show me how I could make deb packages. In the near future, I will make a step-by-step video tutorial in Youtube.

For video acceleration, you need to stick with Bookworm.

Has anybody tried compiling mpv-0.35 + PR14690 within Trixie and ffmpeg 7.x.x? If anyone is curious... mpv-0.37 fails in the compilation step in ad-spdif.c due to an incompatible pointer But mpv-0.38 (without patches) compiles successfully

Dont write that "fbi works correctly", when it is not. The display remains white, and the kernel doesn't show any errors. * Re-check your wiring * Disconnect the touch part of the LCD pins * Try reversing the polarity: dc-gpios = <&pio 2 6 1>; << change the 1 to 0 reset-gpios = <&pio 2 9 1>; << change the 1 to 0 If the CPU is successful sending the reset signal, the data/command, the chip select and any bytes through SPI, at least the LCD should turn black.

I got my issue resolved with labwc+greetd+nwg-hello See this link https://github.com/nwg-piotr/nwg-hello/issues/43 Please check it and post any corrections if needed Getting rpi-greeter (no python) and wf-panel-pi (combines panel and launcher in compact form) would be ideal, but not resolved yet. If anyone is interested in getting rpi-greeter working, this is my partial progress, and I still cannot make it start under lightdm, without any X11: sudo apt install lightdm accountsservice polkitd sudo apt install libgtk-layer-shell-dev librsvg2-common sudo apt install gnome-common gobject-introspection gir1.2-gtk-3.0 These might be needed. I installed them the day after I installed greetd and ngw-hello. Note: I am working from a minimal debian trixie image appmenu-gtk-module-common libaccountsservice-dev gir1.2-accountsservice-1.0 liblightdm-gobject-dev liblightdm-gobject-1-0 libgtk-3-dev gnome-common nasm ~$ mkdir rpi-greeter ; cd rpi-greeter wget https://github.com/raspberrypi-ui/pi-greeter/archive/refs/heads/master.zip unzip master.zip ; cd rpi-greeter-master autogen.sh ./configure make sudo make install Change /etc/lightdm/lightdm.conf with: greeter-session=pi-greeter-labwc Test with: $ sudo lightdm --test-mode --debug or $ sudo systemctl start lightdm $ journalctl -b -u lightdm.service The error is: Oct 13 22:01:49 orangepizero3 lightdm[845]: Error updating user /org/freedesktop/Accounts/User1000: GDBus.Error:org.freedesktop.Accounts.Error.PermissionDenied: Not authorized: GDBus.Error:org.freedesktop.DBus.Error.ServiceUnknown: The name org.freedesktop.PolicyKit1 was not provided by any .service files DEBUG: Could not run plymouth --ping: Failed to execute child process ?plymouth? (No such file or directory) I think I am very close to getting rpi-greeter working. What could be missing? I see that in a raspberry pi, the folder /etc/xdg/labwc-greeter/ exists, with 3 files inside, but in armbian, it doesn't exist.
