Search my threads with keyword "ili9341". Post a photo of your wiring, a schematic, and what did you try within armbian... in this thread.

That will definitely make you not get hardware accelerated video Make sure to follow the 3 commands to install the custom repo, its certificate and higher priority: sudo wget http://apt.undo.it:7242/apt.undo.it.asc -O /etc/apt/trusted.gpg.d/apt.undo.it.asc . /etc/os-release && echo "deb http://apt.undo.it:7242 $VERSION_CODENAME main" | sudo tee /etc/apt/sources.list.d/apt.undo.it.list $ echo -e "Package: *\nPin: release o=apt.undo.it\nPin-Priority: 600" | sudo tee /etc/apt/preferences.d/apt-undo-it sudo apt update Then check that the new custom dpkgs are available for install/upgrade apt list ffmpeg-whatever Here's how I force install a specific version: sudo apt install packagename=nn.nn.n

Share your displaying configuration by running "neofetch" and post it here. If your X11 is running on top of framebuffer, instead of DRM, it wont work. I also would like to get more debug from cedrus, linux's v4l2... but at least you can add -v to mpv to get more debug You only need the ffmpeg plugins offered by the original poster of the v4l2-request thread This is tested with mpv player only. v4l2-util and -ctl are only useful for webcams and video capture devices. v4l2loopback is not involved here. I don't have it I have an orange pi zero LTS, but I havent tested it there (I would use an SPI LCD, since it doesn't have an HDMI prot)

For debian problems, do what I do: Get the cheapest raspberry Recreate the problem Ask the question in the raspberry forum Apply solution to Armbian XD

XD take your concerns to Canonical

With the armbian build system, you can build either Bookworm or Trixie You will always get the latest Bookworm or the latest Trixie packages in a freshly built armbian OS. This is what's meant by "always rolling release"... not to be understood as "always sid or Trixie". Independently, the armbian build system will let you choose a stable Linux version, or the latest available from Armbian (edge).

You are still using an old Linux. You need Linux 6.13 or newer. You need to build your own Armbian OS. Also, don't forget the cma=256M kernel argument

Get the microsd card mounted in your linux laptop Open /boot/armbianEnv.txt Add the line: extraargs=plymouth.enable=0 disablehooks=plymouth https://wiki.archlinux.org/title/Plymouth When you get booted in your armbian OS: sudo apt remove plymouth

I don't know anything about this patch, but check this: * Linux version you are using, vs Linux version corneliius has used * Try deleting the hunk in the patch that caused the problem you saw, and see if other hunks cause patch failures * If it is only one hunk causing the problem, look at the file that is affected by the patch drivers/auxdisplay/Makefile: do the lines mentioned in the hunk exist in the Makefile? In the expected line number?

Find a DTS that uses compatible="waveshare,rpi-lcd-35" and try again (I don't use that LCD, so I am not sure... but I know it is special because it contains a SPI-to-parallel chip)

Can you try if any of the H3 images from libre-elec would get you video acceleration? https://libreelec.tv/downloads/allwinner/ i once tried the orange pi pc image in my orange pi zero lts (h3) and it worked

Bookworm is going to remain as an armbian-build option, right?

My main theory is that linux 6.12 doesn't have the v4l2 improvements needed for hw acceleration, that you can only get with linux 6.13.... The link i published explains that.

Did you compile your armbian OS with linux edge 6.15.x, bookworm, xfce? https://forum.armbian.com/topic/32449-repository-for-v4l2request-hardware-video-decoding-rockchip-allwinner/#findComment-216587

Your gpios lines are declaring reset="i6" and dc="h4"... is that correct? At this point, we can see that all pins are correctly defined and connected. Maybe wire length issue? Bad terminal connection? My wires are 15cm long... directly connected with dupont connectors.

Boot while looking at the serial output, what do you see?

Self compiled Armbian Bookworm + XFCE with Linux Edge 6.15.x Then follow all the instructions in https://forum.armbian.com/topic/32449-repository-for-v4l2request-hardware-video-decoding-rockchip-allwinner/#findComment-176981 Then add extraargs=cma=256M to armbianEnv.txt

If it doesn't work, compile your own Armbian with EDGE linux (what worked for me). Stay away from Trixie at this time (its mpv doesn't work as well as Bookworm's)

THANK YOU

I get this warning because I removed lightdm-gtk-greeter.desktop... what should I do to not expect the file? roberto@orangepizero3:~$ update-alternatives --display lightdm-greeter update-alternatives: warning: alternative /usr/share/xgreeters/lightdm-gtk-greeter.desktop (part of link group lightdm-greeter) doesn't exist; removing from list of alternatives lightdm-greeter - auto mode link best version is /usr/local/share/xgreeters/pi-greeter.desktop link currently points to /usr/local/share/xgreeters/pi-greeter.desktop link lightdm-greeter is /usr/share/xgreeters/lightdm-greeter.desktop /usr/local/share/xgreeters/pi-greeter.desktop - priority 70 After some research of greeters, I see that the default greeter is compatible with wayland https://github.com/Xubuntu/lightdm-gtk-greeter I have been working as if lightdm requires X11 (which I need to avoid), and so I wanted to used pi-greeter Does anybody have lightdm+gtkgreeter in a pure wayland setup? No X11

What is the difference between --hwdec=v4l2request and --hwdec=drm ? And drmprime, drmprime_overlay, and auto? Is the v4l2request absent from Trixie's mpv, due to a pre-compile configuration, or was it removed from the mpv source code?

Are you using the same GPIO wiring as I am? Previously, I was using different GPIO for the chip select, and touch wasn't working... now with my current GPIO in my DTS, it works perfectly.

Hello, I am trying to have a graphical login screen for my orange pi zero 3 with ili9488 LCD screen. A problem I have is that X11 can't start with the LCD driver... so I need to stay 100% wayland. I was able to compile and run labwc with these instructions: https://forum.armbian.com/topic/53797-labwc-wayland-crashes-on-exit/#findComment-223267 Labwc runs well on a HDMI screen and in the small ili9488 screen Next, I found this graphical login, which is made to install on top of lightdm: https://github.com/raspberrypi-ui/pi-greeter/tree/master Compilation rerequisites: sudo apt install gobject-introspection libgtk-3-dev liblightdm-gobject-dev libgtk-layer-shell-dev Lightdm requirement: sudo apt install accountsservice Compile it: $ autogen.sh $ ./configure $ make $ sudo make install There are some hints to post-install in the debian package postint: $ update-alternatives --install /usr/share/xgreeters/lightdm-greeter.desktop lightdm-greeter /usr/share/xgreeters/pi-greeter.desktop 70 In lightdm.conf: greeter-session=pi-greeter I check the lightdm configuration: $ update-alternatives --display lightdm-greeter lightdm-greeter - auto mode link best version is /usr/local/share/xgreeters/pi-greeter.desktop link currently points to /usr/local/share/xgreeters/pi-greeter.desktop link lightdm-greeter is /usr/share/xgreeters/lightdm-greeter.desktop /usr/local/share/xgreeters/pi-greeter.desktop - priority 70 /usr/share/xgreeters/lightdm-gtk-greeter.desktop - priority 60 Then I erase the link to lightdm-gtk: sudo rm /usr/share/xgreeters/lightdm-gtk-greeter.desktop When I try to start lightdm with sudo systemctl start lightdm, fails with: Job for lightdm.service failed because the control process exited with error code.

Does anybody have experience in installing pi-greet, or another greeter that would work in wayland? I need it to be efficient THANK YOU!

Share your DTS, maybe you missed something Run: dmesg | grep -E 'spi|panel' and post the result I already saw the online store... it is the same LCD that I use (I have both 3.5" and 4.0" and they work with the same DTS and bin file)

Make sure to power the VCC and LED with 3.3v, not 5v
