Q Light Controller+

OK -

So I know I'm doing something stupid....

I've installed the image on my RaspPi. It booted fine and I get the command prompt after boot...but no GUI for QLC+.

What am I doing wrong?

Display is connected....

Appreciate any help!

Thanks!

OK. I'll try and figure out how to code "sleep 3" and where to place it.

Testing the limits of my coding knowledge here.

It really shouldn't be hard to do. on your RPi QLC+ SD card there's a rootfs partition, and there you'll find /usr/sbin/qlcplus-start.sh which is an executable shell script that can be edited with a text editor (either do that on a PC with SD Card reader (EDIT: hm, won't work in case rootfs is ext2 or another linux filesystem) or on the running system with root privileges in the terminal, using e.g. nano, vim or joe console editors (not sure what's included in the image but there should be one).
In the other thread, further on top, Massimo tells where to put the "sleep 3" line, just before line 22 or even line 21 (that shouldn't make a difference).

Sorry as I'm thick - is the syntax "Sleep 3;" or just "Sleep 3" or "sleep (3)" or rather, is it something else?

Thanks!

It's exactly as written, lowercase and no parantheses "sleep 3".

Thanks.

Made the change and sill no luck.

I can see the Pi booting on the monitor as it runs through all the scripts, etc. But then I just get the linux command prompt, no QLC+ GUI.

OK,

Please forgive my ignorance in advance....but maybe I'm not understanding what I should expect to see.

Should I even expect to see the GUI on my screen or do I need to connect via a web browser?

There should be a GUI on screen, but running fullscreen without X11 (using EGL).

What happens if you launch /usr/sbin/qlcplus-start.sh from your command prompt?

It pauses for a few seconds and then displays the command prompt again.

Which Raspberry Pi model are you using?

ok. Tried launching again from the command prompt. I get a series of messages (including only the most pertinent):

The official image must work out of the box on a Raspberry Pi 4.
Can you please try with an older image like 20230519?
Thanks
