Thank you again for your answer. I switched back to Linux Mint 19.3 Cinnamon having the same issue. Is there also a mainline kernel available for this distribution?

When I try, the shutdown screen appears. The first two dots below the ubuntu logo, turn orange and then it freezes. Reboot works fine. The debug-shell is no use, because at the freeze point I can't type in commands. When I press ESC to see what's going on during shutdown, the last message to appear ist "[Some weird number] reboot: power down. Last time I pressed ESC during shutdown the "weird number" was 85.270119. I also tried to shutdown with the terminal commands "sudo shut
down now", "sudo shutdown -P now", "sudo shutdown -h now", "poweroff" and "sudo poweroff -f". All of them had the effect as describe above except the command "sudo poweroff -f". After I typed in the command, I authenticated and following messages appeared: "Powering off...". At this point it freezed. I could still see the desktop and every visible window, but I couldn't perform any actions; not even keyboard shortcuts worked. It also did not help to change 'GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"' in /etc/default/grub to 'GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi=force"' and run "update-grub". Once the following command combo did work: "sudo swapoff -a && systemctl poweroff", but the I reinstalled Ubuntu and now it doesn't work any more. In the application "Additional Drivers" I selected the proprietary and tested driver of NVIDIA, but I can't to this for my WLAN-Card (correct word?), because the "Additional Drivers" says it's not working, but my WLAN works fine. I've got only 
Bluetooth problems. The displayed name of the WLAN-Card is: "Intel Corporation: Wireless 7260 (Dual Band Wireless-AC 7260)". I also tried to manually install a driver it didn't help. When I wake up the laptop, a black screen appears with some error messages, but only for a very short time so I can't make a photo of it. I tried once and the text was unreadable. I have the latest BIOS and my Computer model is MSI PX60 2QD. It doesn't work with Arch Linux either.
