OK,
I'm getting better results with the following settings:
ALREADY TRIED:
Disable VT-d(Intel Virtualization Technologies) in the BIOS
/etc/default/grub:
GRUB_CMDLINE_LINUX_DEFAULT="quiet intel_pstate=disable"
then
$ sudo update-grub
and
/etc/modprobe.d/i915.conf:
options i915 semaphores=1
then
$ sudo update-initramfs -u
NOT TRIED:
/etc/X11/xorg.conf.d/20-intel.conf

symptoms are:
- The screen freezes

see:
