Have you looked at setting AutoAddGPU to false? AutoBindGPU is too
late -- that's when you already have a GPU, whether to bind it to the
primary device (/screen/whatever). You need to not have a GPU in the
first place.
Yes, I tried AutoAddGPU=false. Then the UDL device was not set up at all.
What I noticed in debugging Xorg via GDB is that the UDL device was
matched to the wrong platform device in xf86platformProbeDev.
[long details deleted]
Now the xserver MR is at https://gitlab.freedesktop.org/xorg/xserver/merge_requests/335
with explaining the same as I wrote in the previous mail in the commit message.
I have also created https://gitlab.freedesktop.org/xorg/xserver/merge_requests/336
to fix the same issue when using BusID for the UDL device.
Best regards,
Zoltán Böszörményi
