Ubuntu – Installation on new laptop DELL Inspiron 5491 freezes


I have a similar laptop to

Ubuntu 19.10 installer doesn't start on my Dell Inspiron 5491

But I am opening another question as the problem I face is different.
The laptop is quite new
and did not find any experience with the Ubuntu installation.

After switching from RAID to AHCI, disabling a secure boot, updating the BIOS, and play around with the BIOS option, I am trying to install Ubuntu 18.04.03.

I am not actually installing it but just using "Try Ubuntu".
I pass to the bootloader the options nomodeset intel_idle.max_state=1 without which the installation stops very early. I've also played around with ipv6.disable.

Everything stops while turning on services(see attached figure).
In particular acpid.service is the last thing I see, then the system freezes.

I suspect it is related to ACPI setup but don't have any clue on how to fix it.
Any suggestion is much appreciated.

I have the same computer and for me it works with "noapic" on Ubuntu 18.04 and 19.10, and with "nolapic" on other distro.

Once 19.10 installed, it works great except the touch screen which is not reconized and the sleeping mode (suspend). I spent hours on it with no sucess for the moment. if you found any tips let me know.
