It's not that I'm ignoring your suggestion, it's just that it's not so simple
to test it. Right now, Xorg can't even see the nvidia GPU. It is "disabled",
so to speak (not exactly, is on and consuming power, but it's invisible for
the system). Only the Intel GPU is visible and this is the driver X loaded,
not nouveau. The proper nvidia driver does not find the nvidia GPU neither.
I've seen two solutions for activating the nvidia GPU in a system with nvidia
All those transformers
seem great, but it takes some time to make them
work. This is not a priority for me at the moment and, since the nvidia GPU is
invisible for the system and the loaded driver is the Intel one, it doesn't
seem like the problems are caused by the video driver, specially if they all
go alway when the touchscreen is off.
But eventually I'll make the nvidia GPU work...
