SPI / Monitor Issue

Hi,

I'm trying to get QLC+ to run on a small 3.5" touchscreen.

I've followed the steps in the guide (section 9.3) and have successfully connected to the SPI display, however when I reboot the Pi, the CLI is on the SPI display and the QLC+ GUI stays on the HDMI monitor (see image)

I have tried rebooting the Pi with HDMI disconnected but it still only shows the CLI on the SPI display.

I have tried changing a few parameters to see if I can fix it myself, but I feel like I'm missing something.

Has anyone else had this problem?

Cheers

Hi, the file

Code: Select all

/usr/sbin/qlcplus-start.sh
is set to start QLC+ on eglfs and HDMI.
Have you modified it?
I think you need to use the Linux framebuffer, so

Code: Select all

-platform linuxfb
oh and there's a check for the presence of HDMI cable so you probably need to remove it
