Error When Trying to Run/Start

[mfranzel]

Hello, I was following the directions here: https://www.thedigitalpictureframe.com/how-to-build-a-gorgeous-digital-photo-frame-with-a-raspberry-pi-based-on-2023-bookworm/ using a RPi4

But when I get to the part where "start_picframe.sh" has to run, it always just gives the error:

"error: XDG_RUNTIME_DIR is invalid or not set in the environment. failed to connect to display"

Do you have any suggestions on how to fix this?

I also have not had any success with: RPI4 Bookworm / Raspberry Pi OS Lite (actually Openhab distribution which is Pi OS Lite with Openhab scripts) Following that guide and https://github.com/helgeerbe/picframe/wiki/Setup-guide-Bookworm-and-Wayland

When I try start_picframe.sh, I get errors: failed to connect to display AssertionError: failed to init sdl2: b'wayland not available'

My monitor displays the console fine. I can show pictures with feh

[mfranzel]

Yep, I get that too. I cannot display photos in ANY way. I also tried Orange Pi and that doesn't work either.

[pippin88]

Progress.

I started again, this time using the Raspberry Pi OS Lite image (not openhabian, which is based on that).

Followed the github guide (https://github.com/helgeerbe/picframe/wiki/Setup-guide-Bookworm-and-Wayland)

I am able to get picframe working if: SSH into RPI I enter the virtual environment source venv_picframe/bin/activate then picframe Pictures display on monitor and cycle as expected

However, auto-starting on boot is not working for me.

(I have named my user openhabian because I plan to manually install openhab later, but this is the Raspberry Pi OS Lite image)

journalctl -g picframe

I got mine working.

Not sure exactly how I ended up getting auto-start on boot to work, but have it working now. I did add export WAYLAND_DISPLAY=wayland-1 export XDG_RUNTIME_DIR=/run/user/1000 to start_picframe.sh

But in the mean-time, I installed openhab/openhabian - doing so stopped picframe working at all (no picframe output to monitor). Eventually I worked out openhabian does tweaks for headless/no display.

So I needed to change /boot/firmware/config.txt back to:

# Enable DRM VC4 V3D driver
dtoverlay=vc4-kms-v3d
max_framebuffers=2

comment out gpu memory (openhabian adds gpu_mem=16)

and now I have picframe working, and openhab working

My start_picframe.sh

#!/bin/bash
wlr-randr --output HDMI-A-1 --off
export SDL_VIDEODRIVER=wayland # sdl has to use wayland
source /home/openhabian/venv_picframe/bin/activate # activate phyton virtual env
export WAYLAND_DISPLAY=wayland-1
export XDG_RUNTIME_DIR=/run/user/1000
picframe &  #start picframe
wlr-randr --output HDMI-A-1 --on

[mfranzel]

@pippin88 I added

export WAYLAND_DISPLAY=wayland-1
export XDG_RUNTIME_DIR=/run/user/1000

And if I type picframe I can get it working, but how did you get it to run automatically?

[pippin88]

Did you change your start_picframe?

See my post above for my version.

[mfranzel]

!/bin/bash

wlr-randr --output HDMI-A-1 --off export SDL_VIDEODRIVER=wayland # sdl has to use wayland source /home/openhabian/venv_picframe/bin/activate # activate phyton virtual env export WAYLAND_DISPLAY=wayland-1 export XDG_RUNTIME_DIR=/run/user/1000 picframe & #start picframe wlr-randr --output HDMI-A-1 --on

@pippin88 I specifically used this from above that you posted.

[pippin88]

What is the output of journalctl after boot? Is there anything about picframe there?

[mfranzel]

Absolutely nothing. I attached it here just in case. journalctl.txt

[helgeerbe]

Using bookworm, I recommend actual still to run it under X and not wayland. https://github.com/helgeerbe/picframe/wiki/Setup-guide-Bookworm-and-X
