get xorg to use DSI (LCD) output of RK3566 device?

Hi.
I am using mara's quartz64-a legacy XFCE build (4.19.220) but on a different device.
Essentially I install the build on a quartz64-a and get it running on a microSD card, then I change the dtb file to one from my device and boot it up.
A linux console and login and displayed on the LCD panel if I limit the inittab to run level 3.
By default the run level is set to 4 which results in just a cursor at the top of the screen.
If I change inittab to run level 3 and the run startx then the device attempts to run xorg and then switched itself off.

This is the xorg log that I'm getting. I can see that it is picking up the LCD panel resolution correctly:-

Can anyone suggest anything?

Code:

Can you please describe what you have tried?
a) installing an OS on a SD card on an hardware: which one? what GPU you had on it?.
b) you then try to boot another hardware (what type) with the SD card from above? what GPU on it?
Not sure if I understood, but personally, I would boot the target hardware with the target distro on a live USB and make the install on the SD. Moving cards from one hardware to another could become weird.
If you want to make an XORG optimal setup (if the target distro dont make it good on your target hardware), I would give a try to KNOPPIX which has a quite good hardware live recognition. Play around and find a setup.

The RK3566 is an ARM SoC which includes a G52 GPU.
Excuse me if I'm wrong but Knoppix only works in Intel like CPUs not ARM devices doesn't it?

Anyway, since posting the question I think I am coming to the conclusion that xorg isn't the right answer anyway.
This is a tablet device so I'm probably better off going for Weston or something like that.
According to the postmarketOS wiki getting Weston to work is the first step in porting to phosh or plasma mobile.

That said if anyone can see a simple way to get xorg/xfce to start up on this tablet then that would still be cool.

Hi pscan,
you were comparing the Xorg output from the production system?

you can also try replacing the xf86-input-libinput package with xf86-input-synaptics

No, I haven't compared the xorg output from my tablet device (above) with that from an quartz64, which is a good point.

That said, my quartz64 is using HDMI output whereas the tablet is using DSI output so it wouldn't exactly be comparing like for like. To achieve like for like I would have to get an LCD screen and hook it up to the DSI port on the quartz64.

Is it possible that xorg choked only due to lack of a mouse?

That said, my quartz64 is using HDMI output whereas the tablet is using DSI output so it wouldn't exactly be comparing like for like. To achieve like for like I would have to get an LCD screen and hook it up to the DSI port on the quartz64.
comparison is expected on one and the same device.

Is it possible to configure a dummy mouse to fool xorg into starting up?
