Nicolò, unfortunately the automatic GPU dumps do not work very well on
newer hardware, since a GPU reset is initialized before the dump is
taken. In order to get the best logs  it would be nice if you could
reproduce with the newest drm-intel-next kernel from
http://kernel.ubuntu.com/~kernel-ppa/mainline/drm-intel-next/ booted
with the kernel option drm.debug=0x02 (after quiet splash), ssh in from
another computer and grab /sys/kernel/debug/dri/0/i915_error_state,
/var/log/Xorg.0.log, and the output of dmesg (which will have more
information than usual, due to the drm.debug=0x02 option). Since this is
triggered by the lid close/open, it may be useful to record the output
of `sudo intel_reg_dumper` before and after lid close/open and also
`sudo intel_gpu_dump` before you close the lid.
