Help needed - Raspberry 4 with the newest image doesent run

Hi Folks,

First of all, many thanks for the big help and your efforts.
Hopefully you can help me

I got a big problem wih my raspberry 4 Version B with the actual image qlcplus_raspios_bookworm_20241101

BTW, the image qlcplus_raspios_bookworm_20240317 have the same effects

The image: qlcplus_raspios_bullseye_20230519 run without any problems


Raspi ist connected via HDMI to a Monitor

I flash the image new, bring it into my raspberry

QLC don´t come up

I logged in and use

Code: Select all

/usr/sbin/qlcplus-start.sh
QLC comes up

I connect the network to the raspi

QLC dont come up, only the terminal message shows up on the monitor

Then I use

Code: Select all

/usr/sbin/qlcplus-start.sh
and QLC comes up, even I can acces the web interface


Connect the network and reboot, QLC don´t come up. In the terminal there is only the login

When I use

Code: Select all

sudo service qlcplus status

Code: Select all

Maggus@Maggus:~ $ sudo qlcplus service status
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.
Available platform plugins are: eglfs, linuxfb, minimal, minimalegl, offscreen, vnc, wayland-egl, wayland, wayland-xcomposite-egl, wayland-xcomposite-glx, xcb
Aborted
So I try to adopt the sleep time, no effect

Again new flashing, same effects

The I disconnect the monitor
Same Messages as before

I read nearly all topic arround this issues, but nothing helps me, to get the actual image running.

Please find the start.sh down here

Hi Massimo,

unfortunately no changes in the behavior :(

I just tested the official image on a second Raspberry Pi 4 to make sure it was working and it starts correctly.
I can see QLC+ starting on HDMI0 and/or HDMI1.
The content of $HOME/.qlcplus.eglfs.json shows "/dev/dri/card1"

Please let me know if it is the same on your device

Hi Massimo,

so triple check

Starting Headless

No Web Access


The content of $HOME/.qlcplus.eglfs.json shows

Code: Select all

{ "device": "/dev/dri/card1" }

Starting at HDMI 0
Only Prompt
No Web Access
The content of $HOME/.qlcplus.eglfs.json shows

Code: Select all

{ "device": "/dev/dri/card1" }
Starting at HDMI 1
Rainbow Screen
Only Prompt
No Web Access

The content of $HOME/.qlcplus.eglfs.json shows

Code: Select all

{ "device": "/dev/dri/card1" }


Using HDMI 1
When I input:

Code: Select all

/usr/sbin/qlcplus-start.sh
via remote (MobaXterm)

QLC comes up in the Moba Xterm Window, even I have web acces

When I go directly via my keyboard to the Raspi, it seems that QLC starts.
But I dont see a GUI, Web Acces is possible

Using HDMI 0

No rainbow window

When I input:

Code: Select all

/usr/sbin/qlcplus-start.sh
via remote (MobaXterm)

QLC comes up in the Moba Xterm Window, even I have web acces

When I go directly via my keyboard to the Raspi, QLC starts.
I see the GUI, Web Access is possible
Even the Wifi configuaration is possible


When I look during the boot process, everything is green.

Regards

Marcus

So again me,
I download the image again, check the checksum and flash it with the RPI Tool to my SD Card.

I only configure the Name and the password at the RPI Tool before I flash.
All Network is at DHCP

The Raspi boot on HDMI 0 and HDMI 1 until to the prompt.
No starting from QLC.

WHen I start QLC with

Code: Select all

/usr/sbin/qlcplus-start.sh
QLC comes up.
I check the IP Adress from the Raspi in my router and can enter the Web Access without any problems.

EDIT
Restart the raspi without any changes
QLC dont come up, no Web Access

I just checked the

Code: Select all

/home/Maggus/.qlcplus/

Code: Select all

{ "device": "/dev/dri/card1" }
is there, wIthout any changes as recommended in the link before


The result of
sudo service qlcplus status

Code: Select all

Maggus@Maggus:~ $ sudo service qlcplus status

Which display are you using?
A TV? A HDMI monitor?
Do you have any chance to try with another display?

However, you previous statement "Starting headless: no web access" leaves me puzzled. At least that should work.
Have you tried to boot without a display, SSH into the RPi and see if QLC+ is running?

Both, I try with both

Do you have any chance to try with another display?
Yes already done

I try this, but QLC does not run

Another research

according to the fact that
Main PID: 892 (code=exited, status=217/USER)

seems that there are user problems,

(Google was my friend BTW)

I check the journal

Code: Select all

 journalctl
And thee comes some messages up, which are might be the reason for the problem

Wait, wait so the issue is that you were changing the user 'pi' password?
Or you changed the username completely?

I change the username and the password at RPI

Just double check it

When I leave everything as it comes up in the RPI

I will not delete this as it can be useful for future reference to other users falling into the same situation.
To be honest, as far as I remember, there should be nothing binding QLC+ to the user 'pi' so I still cannot explain why it doesn't start.
Maybe it's a systemd issue but at the moment I am working on other topics and cannot look into this.

Hi Massimo,

the delete is only for the comment where I write "please delete me", because there was a lot of typos

So for the moment I can only use the user "pi" and wait if something is comming up.

Anyhow, thank you for your help.

Regards

Marcus

The Connection QLCPlus shows up.

Hi, just to add that I ran into the same issue, when choosing a default username other than pi. Flashed the SD again with default user pi and all is well.
