I was saying that because several xorg functions were
not activated (initializations, processing of EDID), which
could means they were not called.

Anyway there are the same list of xorg packages in the
working BE and the updated one.

I would not blame the driver, as all versions tried behave
properly with the initial BE. Also I can imagine the
interface between the driver and xorg has been tested on
other configurations, so the issue must be elsewhere.

I am keeping the configuration as is until somebody has
something else to suggest or you have an updated Xorg.
No need to rush it out, I will use the working BE in the
meantime.

Thank you for your help.
