It is really not within my power to get a shell or gui without acpi=off. Following your suggestion, I provoked such a failed boot by temporarily removing acpi=off from the boot parameters. Afterwards I ran "journalctl -b -1" to get the logs of that failed attempt. For your reference, I attached them to this comment.

I was seeking for help on ask ubuntu (https://askubuntu.com/questions/1245783/problems-with-touchpad-in-ubuntu-20-04-with-acpi-off), but didn't receive any. So I installed xubuntu 20.04 nevertheless and I am now working without touchpad using both mouse and keyboard as replacements. The installation failed with the 20.04 xubuntu stick (with some grub error message), so I used an 18.04 xubuntu stick which worked. Afterwards I upgraded the system which also included some trouble with grub but I could leave grub as it was so that the system is now mostly functional (apart from the touchpad and that shutdowns do not really work, but that's not too bad).
